get_h_errno(3sock)

get_h_errno, set_h_errno -- get/set h_errno value

Synopsis

cc [options] file -lsocket -lnsl


#include <sys/socket.h>

int get_h_errno(void);

int set_h_errno(int);

Description

The get_h_errno and set_h_errno functions are used in multi-threaded applications that use the Socket Interface to set and return the value in h_errno.

These functions are required by applications compiled with the -Kthread option if the user needs to set the thread-specific version of h_errno.

Files

/usr/lib/libsocket.so: Socket Library (shared object)

Usage

While get_h_errno and set_h_errno are designed for use in multi-threaded applications, they are available for used in non-reentrant code and may be incorporated if a need is anticipated to convert to reentrant code later on.
