Data Structures

struct  ast_str
 The descriptor of a dynamic string XXX storage will be optimized later if needed We use the ts field to indicate the type of storage. Three special constants indicate malloc, ast_alloca() or static variables, all other values indicate a struct ast_threadstorage pointer. More...

Core functionality of ast_str_(set|append)_va.

The arguments to this function are the same as those described for ast_str_set_va except for an addition argument, append. If append is non-zero, this will append to the current string instead of writing over it.

AST_DYNSTR_BUILD_RETRY is a legacy define. It should probably never again be used.

A return of AST_DYNSTR_BUILD_FAILED indicates a memory allocation error.

A return value greater than or equal to zero indicates the number of characters that have been written, not including the terminating '\0'. In the append case, this only includes the number of characters appended.

Note
This function should never need to be called directly. It should through calling one of the other functions or macros defined in this file.

core handler for dynamic strings. This is not meant to be called directly, but rather through the various wrapper macros ast_str_set(...) ast_str_append(...) ast_str_set_va(...) ast_str_append_va(...)

◆ ast_build_string()

int ast_build_string ( char **  buffer,
size_t *  space,
const char *  fmt,
  ... 
)

Build a string in a buffer, designed to be called repeatedly.

Note
This method is not recommended. New code should use ast_str_*() instead.

This is a wrapper for snprintf, that properly handles the buffer pointer and buffer space available.

Parameters
buffercurrent position in buffer to place string into (will be updated on return)
spaceremaining space in buffer (will be updated on return)
fmtprintf-style format string
Return values
0on success
non-zeroon failure.

◆ ast_copy_string()

void ast_copy_string ( char *  dst,
const char *  src,
size_t  size 
)
inline

Size-limited null-terminating string copy.

Parameters
dstThe destination buffer.
srcThe source string
sizeThe size of the destination buffer
Returns
Nothing.

This is similar to strncpy, with two important differences:

  • the destination buffer will always be null-terminated
  • the destination buffer is not filled with zeros past the copied string length These differences make it slightly more efficient, and safer to use since it will not leave the destination buffer unterminated. There is no need to pass an artificially reduced buffer size to this function (unlike strncpy), and the buffer does not need to be initialized to zeroes prior to calling this function.
Examples:
/usr/src/asterisk-18.5.0/include/asterisk/strings.h, and /usr/src/asterisk-18.5.0/main/app.c.

◆ ast_generate_random_string()

char* ast_generate_random_string ( char *  buf,
size_t  size 
)

Create a pseudo-random string of a fixed length.

This function is useful for generating a string whose randomness does not need to be across all time and space, does not need to be cryptographically secure, and needs to fit in a limited space.

This function will write a null byte at the final position in the buffer (buf[size - 1]). So if you pass in a size of 10, then this will generate a random 9-character string.

Parameters
bufBuffer to write random string into.
sizeThe size of the buffer.
Returns
A pointer to buf

/usr/src/asterisk-18.5.0/include/asterisk/strings.h.

Parameters
buffer[IN/OUT] A pointer to a char * string with either Unix or Windows line endings
Returns
The "next" line
Warning
The original string and *buffer will be modified.

Both '
' and '
' are treated as single delimiters but consecutive occurrances of the delimiters are NOT considered to be a single delimiter. This preserves blank lines in the input.

MacOS line endings ('') are not supported at this time.

◆ ast_str_append()

int ast_str_append ( struct ast_str **  buf,
ssize_t  max_len,
const char *  fmt,
  ... 
)
inline

Append to a thread local dynamic string.

Note
Care should be taken when using this function. The function can result in reallocating the ast_str. If a pointer to the ast_str is passed by value to a function that calls ast_str_append(), then the original ast_str pointer may be invalidated due to a reallocation.

The arguments, return values, and usage of this function are the same as ast_str_set(), but the new data is appended to the current value.

Examples:
/usr/src/asterisk-18.5.0/include/asterisk/strings.h.

◆ ast_str_set()

int ast_str_set ( struct ast_str **  buf,
ssize_t  max_len,
const char *  fmt,
  ... 
)
inline

Set a dynamic string using variable arguments.

Note
Care should be taken when using this function. The function can result in reallocating the ast_str. If a pointer to the ast_str is passed by value to a function that calls ast_str_set(), then the original ast_str pointer may be invalidated due to a reallocation.
Parameters
bufThis is the address of a pointer to a struct ast_str which should have been retrieved using ast_str_thread_get. It will need to be updated in the case that the buffer has to be reallocated to accomodate a longer string than what it currently has space for.
max_lenThis is the maximum length to allow the string buffer to grow to. If this is set to 0, then there is no maximum length. If set to -1, we are bound to the current maximum length.
fmtThis is the format string (printf style)
Returns
The return value of this function is the same as that of the printf family of functions.

All the rest is the same as ast_str_set_va()

◆ ast_strings_equal()

int ast_strings_equal ( const char *  str1,
const char *  str2 
)

Compare strings for equality checking for NULL.

Since
16.3.0

This function considers NULL values as non-strings, thus a false condition. This means that it will return false if one, or both of the given values are NULL (i.e. two NULLs are not equal strings).

Parameters
str1The string to compare to str2
str2The string to compare to str1
Returns
true if valid strings and equal, false otherwise.

◆ ast_strings_match()

int ast_strings_match ( const char *  left,
const char *  op,
const char *  right 
)

Compares 2 strings using realtime-style operators.

Since
13.9.0
Parameters
leftThe left side of the equation
opThe operator to apply
rightThe right side of the equation
Return values
1matches
0doesn't match

Operators: "=", "!=", "<", "<=", ">", ">=": If both left and right can be converted to float, then they will be compared as such. Otherwise the result will be derived from strcmp(left, right). "regex": The right value will be compiled as a regular expression and matched against the left value. "like": Any '' character in the right value will be converted to '.*' and the resulting string will be handled as a regex. NULL , "": If the right value starts and ends with a '/' then it will be processed as a regex. Otherwise, same as "=".

◆ ast_strip_quoted()

char* ast_strip_quoted ( char *  s,
const char *  beg_quotes,
const char *  end_quotes 
)

Strip leading/trailing whitespace and quotes from a string.

Parameters
sThe string to be stripped (will be modified).
beg_quotesThe list of possible beginning quote characters.
end_quotesThe list of matching ending quote characters.
Returns
The stripped string.

This functions strips all leading and trailing whitespace characters from the input string, and returns a pointer to the resulting string. The string is modified in place.

It can also remove beginning and ending quote (or quote-like) characters, in matching pairs. If the first character of the string matches any character in beg_quotes, and the last character of the string is the matching character in end_quotes, then they are removed from the string.

Examples:

ast_strip_quoted(buf, "\"", "\"");
ast_strip_quoted(buf, "'", "'");
ast_strip_quoted(buf, "[{(", "]})");
Examples:
/usr/src/asterisk-18.5.0/include/asterisk/strings.h.

◆ ast_strsep()

char* ast_strsep ( char **  s,
const char  sep,
uint32_t  flags 
)

Act like strsep but ignore separators inside quotes.

Parameters
sPointer to address of the string to be processed. Will be modified and can't be constant.
sepA single character delimiter.
flagsControls post-processing of the result. AST_STRSEP_TRIM trims all leading and trailing whitespace from the result. AST_STRSEP_STRIP does a trim then strips the outermost quotes. You may want to trim again after the strip. Just OR both the TRIM and STRIP flags. AST_STRSEP_UNESCAPE unescapes '\' sequences. AST_STRSEP_ALL does all of the above processing.
Returns
The next token or NULL if done or if there are more than 8 levels of nested quotes.

This function acts like strsep with three exceptions... The separator is a single character instead of a string. Separators inside quotes are treated literally instead of like separators. You can elect to have leading and trailing whitespace and quotes stripped from the result and have '\' sequences unescaped.

Like strsep, ast_strsep maintains no internal state and you can call it recursively using different separators on the same storage.

Also like strsep, for consistent results, consecutive separators are not collapsed so you may get an empty string as a valid result.

Examples:

char *mystr = ast_strdupa("abc=def,ghi='zzz=yyy,456',jkl");
char *token, *token2, *token3;
while((token = ast_strsep(&mystr, ',', AST_SEP_STRIP))) {
// 1st token will be aaa=def
// 2nd token will be ghi='zzz=yyy,456'
while((token2 = ast_strsep(&token, '=', AST_SEP_STRIP))) {
// 1st token2 will be ghi
// 2nd token2 will be zzz=yyy,456
while((token3 = ast_strsep(&token2, ',', AST_SEP_STRIP))) {
// 1st token3 will be zzz=yyy
// 2nd token3 will be 456
// and so on
}
}
// 3rd token will be jkl
}
