Read a character from stdin
#include <stdio.h> int fgetchar( void );
libc
The fgetchar() function is the same as fgetc() with an argument of stdin.
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).
#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; }
