PUTC(3S)                COMMAND REFERENCE                PUTC(3S)



NAME
     putc, putchar, fputc, putw - put character or word on a
     stream

SYNOPSIS
     #include <stdio.h>

     int putc(c, stream)
     char c;
     FILE *stream;

     putchar(c)

     fputc(c, stream)
     FILE *stream;

     putw(w, stream)
     FILE *stream;

DESCRIPTION
     Putc appends the character c to the named output stream.  It
     returns the character written.

     Putchar(c) is defined as putc(c, stdout).

     Fputc behaves like putc, but is a genuine function rather
     than a macro.

     Putw appends word (that is, int) w to the output stream.  It
     returns the word written.  Putw neither assumes nor causes
     special alignment in the file.

DIAGNOSTICS
     These functions return the constant EOF upon error.  Since
     this is a good integer, ferror(3s) should be used to detect
     putw errors.

CAVEATS
     Because it is implemented as a macro, putc treats a stream
     argument with side effects improperly.  In particular

          putc(c, *f++);

     doesn't work sensibly.

     Errors can occur long after the call to putc.

SEE ALSO
     fopen(3s), fclose(3s), getc(3s), puts(3s), printf(3s),
     fread(3s).
