KCGI_WRITER_PUTC(3)

NAME
kcgi_writer_putc - write into a writer

LIBRARY
libkcgi

SYNOPSIS
#include <sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>
enum kcgi_err
kcgi_writer_putc(struct kcgi_writer *writer, char c);

DESCRIPTION
The kcgi_writer_putc() function writes character c to a writer channel opened by kcgi_writer_get(3). This allows writing after kcgi_writer_disable(3), unlike khttp_write(3). kcgi_writer_putc() is backed by kcgi_writer_write(3).

RETURN VALUES
Returns an enum kcgi_err indicating the error state.

KCGI_OK
    Success (not an error).

KCGI_ENOMEM
    Internal memory allocation failure.

KCGI_HUP
    The output connection has been terminated. For FastCGI connections, the current connection should be released with khttp_free(3) and parse loop reentered.

KCGI_FORM
    The connection is still expecting headers with khttp_head(3). Indicates that khttp_body(3) did not return with success or was not invoked. For FastCGI connections, the current connection should be released with khttp_free(3) and parse loop reentered.

KCGI_SYSTEM
    Internal system error writing to the output stream.
