getc_unlocked()

Synopsis:

#include <stdio.h>

int getc_unlocked( FILE *fp );

Arguments:

fp: The stream you want to get the character from.

Library:

libc

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

Description:

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

Returns:

The next character from the input stream pointed to by fp, 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.
