getchar_unlocked()

Get a character from stdin

Synopsis:

#include <stdio.h>

int getchar_unlocked( void );

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

The getchar_unlocked() function is a thread-unsafe version of getchar(). You can use it safely only when the invoking thread has locked stdin using flockfile() (or ftrylockfile()) and funlockfile().

Returns:

The next character from the input stream pointed to by stdin, cast as (int)(unsigned char), or EOF if an end-of-file or error condition occurs (errno is set).


Note: Use feof() or ferror() to distinguish an end-of-file condition from an error.

Classification:

POSIX 1003.1 TSF

Safety:
Cancellation point Yes
Interrupt handler No
Signal handler No
Thread No
