fputchar()
Write a character to stdout
Synopsis:
#include <stdio.h>
int fputchar( int c );
Arguments:
- c
- The character you want to write.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The fputchar() function writes the character specified by c, cast as (int)(unsigned char), to stdout. It's equivalent to putchar() and to:
fputc( c, stdout );
Returns:
The character written, cast as (int)(unsigned char), or EOF if an error occurred (errno is set).
Examples:
#include <stdio.h> #include <stdlib.h> int main( void ) { FILE *fp; int c; fp = fopen( "file", "r" ); if( fp != NULL ) { c = fgetc( fp ); while( c != EOF ) { fputchar( c ); c = fgetc( fp ); } fclose( fp ); return EXIT_SUCCESS; } return EXIT_FAILURE; }
Classification:
Safety: | |

Cancellation point | Yes |
Interrupt handler | No |
Signal handler | No |
Thread | Yes |
Caveats:
If c is negative, the value returned by this function isn't equal to c — unless c is -1 and an error occurred :-)
