man http_strerror (Fonctions bibliothèques) - Returns a pointer to the current error description message.
NAME
http_strerror - Returns a pointer to the current error description message.
SYNOPSIS
#include <http_fetcher.h>
const char *http_strerror();
DESCRIPTION
Returns a pointer to the current error description message regarding the most recent error encountered within an HTTP Fetcher call.
Any HTTP Fetcher function that returns -1 can be
investigated by using http_strerror.
The message pointed to is only guaranteed to be valid until the next call to http_strerror, so if you need to preserve the message you should make a copy of it.
RETURN VALUE
Returns a pointer to a descriptive error message.
