fputc, putc, putchar, putw - output a character or word to a stream
int fputc (int c, FILE *stream);
int putc (int c, FILE *stream);
int putchar (int c);
int putw (int w, FILE *stream);
The fputc function writes the character c (converted to an ''unsigned
char'') to the output stream pointed to by stream.
Putc acts essentially identically to fputc, but is a macro that expands
in-line. It may evaluate stream more than once, so arguments given to
putc should not be expressions with potential side effects.
Putchar is identical to putc with an output stream of stdout.
The putw function writes the specified int to the named output stream.
The functions, fputc, putc and putchar return the character written.
If an error occurs, the value EOF is returned. The putw function
returns 0 on success; EOF is returned if a write error occurs, or if an
attempt is made to write a read-only stream.
ferror(3), fopen(3), getc(3), stdio(3)
The functions fputc, putc, and putchar, conform to ANSI/C. A function
putw function appeared in Version 6 AT&T UNIX.
The size and byte order of an int varies from one machine to another,
and putw is not recommended for portable applications.
