fputc(3f) [bsd man page]

NAME
putc, fputc - write a character to a fortran logical unit SYNOPSIS
integer function putc (char) character char integer function fputc (lunit, char) character char DESCRIPTION
These funtions write a character to the file associated with a fortran logical unit bypassing normal fortran I/O. Putc writes to logical unit 6, normally connected to the control terminal output. The value of each function will be zero unless some error occurred; a system error code otherwise. See perror(3F). FILES

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. It may be used to save on object text. Putw appends word (i.e. int) w to the output stream. It returns the word written. Putw neither assumes nor causes special alignment in the file. The standard stream stdout is normally buffered if and only if the output does not refer to a terminal; this default may be changed by set- buf(3). The standard stream stderr is by default unbuffered unconditionally, but use of freopen (see fopen(3)) will cause it to become buffered; setbuf, again, will set the state to whatever is desired. When an output stream is unbuffered information appears on the desti- nation file or terminal as soon as written; when it is buffered many characters are saved up and written as a block. Fflush (see fclose(3)) may be used to force the block out early. SEE ALSO
fopen(3), fclose(3), getc(3), puts(3), printf(3), fread(3) DIAGNOSTICS
These functions return the constant EOF upon error. Since this is a good integer, ferror(3) should be used to detect putw errors. BUGS
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. PUTC(3S)
