fgetchar()

Read a character from stdin

Synopsis:

#include <stdio.h>

int fgetchar( void );

Library:

libc

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

Description:

The fgetchar() function is the same as fgetc() with an argument of stdin.

Returns:

The next character from stdin, cast as (int)(unsigned char), EOF if end-of-file has been reached on stdin or if an error occurs (errno is set).

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

Examples:

#include <stdio.h>
#include <stdlib.h>

int main( void )
{
    FILE *fp;
    int c;

    fp = freopen( "file", "r", stdin );
    if( fp != NULL ) {
        while( (c = fgetchar()) != EOF ) {
            fputchar(c);
        }
        fclose( fp );
        
        return EXIT_SUCCESS;
    }
    
    return EXIT_FAILURE;
}
