Get the next character from a file
#include <stdio.h> int getc( FILE* fp );
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The getc() macro gets the next character from the stream designated by fp. The character is returned as an int value.
The next character from the stream fp, 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; fp = fopen( "file", "r" ); if( fp != NULL ) { while( (c = getc( fp )) != EOF ) { putchar(c); } fclose( fp ); return EXIT_SUCCESS; } return EXIT_FAILURE; }
