The gai_strerror() function returns a text string describing an error value for the getaddrinfo(3XNET) and getnameinfo(3XNET) 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_BADFLAGS
EAI_FAIL
EAI_FAMILY
EAI_MEMORY
EAI_NONAME
EAI_SERVICE
EAI_SOCKTYPE
EAI_SYSTEM
the function return value points to a string describing the error. If the argument is not one of those values, the function returns a pointer to a string whose contents indicate an unknown error.
Upon successful completion, gai_strerror() returns a pointer to a string describing the error value.
No errors are defined.
