KCGI_WRITER_WRITE(3) Library Functions Manual KCGI_WRITER_WRITE(3)
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.
