Putc writes a character to a specified stream at the current position; putchar writes to stdout.

#include <stdio.h>

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

#include <wchar.h>
wint_t putwc(wchar_t c, FILE *stream);
wint_t putwchar(wchar_t c);

Parameters

c

Character to be written.

stream

Pointer to FILE structure.

Remarks

putchar is identical to:

putc (c, stdout)

Any integer can be passed to putc, but it only writes the lower 8 bits.

These functions are implemented as both macros and functions.

putwc and putwchar are wide-character versions of putc and putchar.

Return Values

The character written.

Success.

EOF.

Failure.
