PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME

       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_BADFLAGS]
	      [EAI_FAIL]
	      [EAI_FAMILY]
	      [EAI_MEMORY]
	      [EAI_NONAME]
	      [EAI_OVERFLOW]
	      [EAI_SERVICE]
	      [EAI_SOCKTYPE]
	      [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

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.

PROLOG

       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME

       h_errno - error return value for network database operations

SYNOPSIS

       #include <netdb.h>

DESCRIPTION

       This method of returning errors is used only in connection with obsolescent functions.

       The <netdb.h> header provides a declaration of h_errno as a modifiable lvalue of type int.

       It is unspecified whether h_errno is a macro or an identifier declared with external linkage. If a macro definition is suppressed in  order
       to access an actual object, or a program defines an identifier with the name h_errno, the behavior is undefined.

RETURN VALUE

       None.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       Applications should obtain the definition of h_errno by the inclusion of the <netdb.h> header.

RATIONALE

       None.

FUTURE DIRECTIONS

       h_errno may be withdrawn in a future version.
