Function Documentation

ast_inet_ntoa()

const char* ast_inet_ntoa

(

struct in_addr

ia

)

thread-safe replacement for inet_ntoa().

Note

It is very important to note that even though this is a thread-safe replacement for inet_ntoa(), it is not reentrant. In a single thread, the result from a previous call to this function is no longer valid once it is called again. If the result from multiple calls to this function need to be kept or used at once, then the result must be copied to a local buffer before calling this function again.

thread-safe replacement for inet_ntoa().
