Read a character from a stream
#include <stdio.h> int fgetc( FILE* fp );
libc
The fgetc() function reads the next character from the stream specified by fp.
The next character from fp, cast as (int)(unsigned char), or EOF if end-of-file has been reached or if an error 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 = fgetc( fp )) != EOF ) {
fputc( c, stdout );
}
fclose( fp );
return EXIT_SUCCESS;
}
return EXIT_FAILURE;
}
