gai_strerror -- address and name information error description SYNOPSIS
#include <netdb.h> const char *gai_strerror(int ecode); DESCRIPTION
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. RETURN VALUE
Upon successful completion, gai_strerror() shall return a pointer to an implementation-defined string. ERRORS
