Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The putchar() function writes the character c,
cast as (int)(unsigned char), to the
stdout stream.
It's equivalent to:
fputc( c, stdout );
The character written, cast as (int)(unsigned char),
or EOF if an error occurs
(errno is set).
#include <stdio.h>
#include <stdlib.h>

FILE *fp;
int c;
fp = fopen( "file", "r" );
c = fgetc( fp );
while( c != EOF ) {
putchar( c );
c = fgetc( fp );
}
fclose( fp );
return EXIT_SUCCESS;
