GAI_STRERROR(3P) POSIX Programmer's Manual GAI_STRERROR(3P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
gai_strerror — address and name information error description
#include <netdb.h>
const char *gai_strerror(int ecode);
The gai_strerror() function shall return a text string describing an
error value for the getaddrinfo() and getnameinfo() functions listed
in the <netdb.h> header.
When the ecode argument is one of the following values listed in the
<netdb.h> header:
[EAI_AGAIN] [EAI_NONAME]
[EAI_BADFLAGS] [EAI_OVERFLOW]
[EAI_FAIL] [EAI_SERVICE]
[EAI_FAMILY] [EAI_SOCKTYPE]
[EAI_MEMORY] [EAI_SYSTEM]
the function return value shall point to a string describing the
error. If the argument is not one of those values, the function
shall return a pointer to a string whose contents indicate an unknown
error.
Upon successful completion, gai_strerror() shall return a pointer to
an implementation-defined string.
No errors are defined.
