clearerr_unlocked
UNLOCKED_STDIO(3) Linux Programmer's Manual UNLOCKED_STDIO(3)NAME
*_unlocked - non-locking stdio functions
SYNOPSIS
#include <stdio.h>
int getc_unlocked(FILE *stream);
int getchar_unlocked(void);
int putc_unlocked(int c, FILE *stream);
int putchar_unlocked(int c);
#define _BSD_SOURCE /* or _SVID_SOURCE or _GNU_SOURCE */
#include <stdio.h>
void clearerr_unlocked(FILE *stream);
int feof_unlocked(FILE *stream);
int ferror_unlocked(FILE *stream);
int fileno_unlocked(FILE *stream);
int fflush_unlocked(FILE *stream);
int fgetc_unlocked(FILE *stream);
int fputc_unlocked(int c, FILE *stream);
size_t fread_unlocked(void *ptr, size_t size, size_t n,
FILE *stream);
size_t fwrite_unlocked(const void *ptr, size_t size, size_t n,
FILE *stream);
#define _GNU_SOURCE
#include <stdio.h>
char *fgets_unlocked(char *s, int n, FILE *stream);
int fputs_unlocked(const char *s, FILE *stream);
#define _GNU_SOURCE
#include <wchar.h>
wint_t getwc_unlocked(FILE *stream);
wint_t getwchar_unlocked(void);
wint_t fgetwc_unlocked(FILE *stream);
wint_t fputwc_unlocked(wchar_t wc, FILE *stream);
wint_t putwc_unlocked(wchar_t wc, FILE *stream);
wint_t putwchar_unlocked(wchar_t wc);
wchar_t *fgetws_unlocked(wchar_t *ws, int n, FILE *stream);
int fputws_unlocked(const wchar_t *ws, FILE *stream);
DESCRIPTION
Each of these functions has the same behaviour as its counterpart without the `_unlocked' suffix, except that they do not use locking (they
do not set locks themselves, and do not test for the presence of locks set by others) and hence are thread-unsafe. See flockfile(3).
CONFORMING TO
The four functions getc_unlocked(), getchar_unlocked(), putc_unlocked(), putchar_unlocked() are in POSIX.1. The nonstandard *_unlocked()
variants occur on a few Unix systems, and are available in recent glibc. They should probably not be used.
