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).
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;
}
