Get a character from stdin
#include <stdio.h> int getchar( void );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The getchar() function is equivalent to getc() on the stdin stream.
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).
#include <stdio.h> #include <stdlib.h> int main( void ) { FILE *fp; int c; /* Get characters from "file" instead of * stdin. */ fp = freopen( "file", "r", stdin ); while( ( c = getchar() ) != EOF ) { putchar(c); } fclose( fp ); return EXIT_SUCCESS; }
