       gai_strerror — address and name information error description

СИНТАКСИС

       #include <netdb.h>

       const char *gai_strerror(int ecode);

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       Upon successful completion, gai_strerror() shall return a pointer
       to an implementation-defined string.
