Detailed Description

Function Documentation

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 In a single thread, the result from a previous call to this function is no longer valid once it is called again.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.
