Writes a character to a stream (putc) or to stdout (putchar).
#include <stdio.h>
int putc( int c, FILE *stream );
int putchar( int c );
| c | Character to be written | |
| stream | Pointer to FILE structure |
The putc routine writes the single character c to the output stream at the current position. The putchar routine is identical to putc(c, stdout).
These routines are implemented as both macros and functions. See “Choosing Between Functions and Macros” for a discussion of how to select between the macro and function forms.
The putc and putchar routines return the character written, or EOF in the case of an error. Any integer can be passed to putc, but only the lower 8 bits are written.

/* PUTC.C: This program uses putc to write buffer to a stream.
* If an error occurs, the program will stop before writing the
* entire buffer.
*/
#include <stdio.h>
void main( void )
{
FILE *stream;
char *p, buffer[] = “This is the line of output\n”;
int ch;
/* Make standard out the stream and write to it. */
stream = stdout;
for( p = buffer; (ch != EOF) && (*p != '\0'); p++ )
ch = putc( *p, stream );
}
This is the line of output
