NAME

kcgi_writer_write — write into a writer

LIBRARY

library “libkcgi”

SYNOPSIS

#include <sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>

enum kcgi_err
kcgi_writer_write(struct kcgi_writer *writer, const void *buf, size_b bufsz);

DESCRIPTION

The kcgi_writer_write() function writes bufsz bytes of buf to a writer channel opened by kcgi_writer_get(3). This allows writing after kcgi_writer_disable(3), unlike khttp_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.
