DIAGNOSTICS
Error return status from getaddrinfo() is zero on success and non-zero on
errors.
Non-zero error codes are defined in
<
netdb.h>, and as follows:
EAI_ADDRFAMILY
Address family for nodename not supported.
EAI_AGAIN
Temporary failure in name resolution.
EAI_BADFLAGS
Invalid value for ai_flags.
EAI_FAIL
Non-recoverable failure in name resolution.
EAI_FAMILY
ai_family not supported.
EAI_MEMORY
Memory allocation failure.
EAI_NODATA
No address associated with nodename.
EAI_NONAME
nodename nor servname provided, or not known.
EAI_SERVICE
servname not supported for ai_socktype.
EAI_SOCKTYPE
ai_socktype not supported.
EAI_SYSTEM
System error returned in errno.
If called with proper argument, gai_strerror() returns a pointer to a
string describing the given error code.
If the argument is not one of
the EAI_xxx values, the function still returns a pointer to a string
whose contents indicate an unknown error.
