#include <stdio.h>

int getc_unlocked(FILE * stream);
int getchar_unlocked(void);
int putc_unlocked(int c, FILE * stream);
int putchar_unlocked(int c);

DESCRIPTION

getc_unlocked , getchar_unlocked , and putchar_unlocked routines are implemented as macros.

They may only safely be used within a scope protected by flockfile (or ftrylockfile ) and funlockedfile .

STANDARDS

These routines conform to the POSIX.1c standards.
