FUNCTION

<<fputc>>---write a character on a stream or file

INDEX

        fputc

INDEX

        _fputc_r

ANSI_SYNOPSIS

        #include <stdio.h>

        int fputc(int <[ch]>, FILE *<[fp]>);

        #include <stdio.h>

        int _fputc_r(struct _rent *<[ptr]>, int <[ch]>, FILE *<[fp]>);

TRAD_SYNOPSIS

        #include <stdio.h>

        int fputc(<[ch]>, <[fp]>)

        int <[ch]>;

        FILE *<[fp]>;

        #include <stdio.h>

        int _fputc_r(<[ptr]>, <[ch]>, <[fp]>)

        struct _reent *<[ptr]>;

        int <[ch]>;

        FILE *<[fp]>;

DESCRIPTION

<<fputc>> converts the argument <[ch]> from an <<int>> to an

<<unsigned char>>, then writes it to the file or stream identified by

<[fp]>.

If the file was opened with append mode (or if the stream cannot

support positioning), then the new character goes at the end of the

file or stream.  Otherwise, the new character is written at the

current value of the position indicator, and the position indicator

oadvances by one.

For a macro version of this function, see <<putc>>.

The <<_fputc_r>> function is simply a reentrant version of <<fputc>>

that takes an additional reentrant structure argument: <[ptr]>.

RETURNS

If successful, <<fputc>> returns its argument <[ch]>.  If an error

intervenes, the result is <<EOF>>.  You can use `<<ferror(<[fp]>)>>' to

query for errors.

PORTABILITY

<<fputc>> is required by ANSI C.

Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,

<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
