KHTTP_WRITE(3)

NAME
khttp_putc, khttp_puts, khttp_write - write HTTP content data for kcgi

LIBRARY
libkcgi

SYNOPSIS
#include <sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>
enum kcgi_err
khttp_putc(struct kreq *req, int c);
enum kcgi_err
khttp_puts(struct kreq *req, const char *cp);
enum kcgi_err
khttp_write(struct kreq *req, const char *buf, size_t sz);

DESCRIPTION
The khttp_putc(), khttp_puts(), and khttp_write() functions write HTTP content for a kcgi(3) context allocated with khttp_parse(3) or khttp_fcgi_parse(3). These functions should only be invoked after khttp_body(3). khttp_putc() emits a single character; khttp_puts() emits a NUL-terminated character string ( note, this does not append a newline like puts(3)), and khttp_write() emits a binary buffer buf of size sz.

Once kcgi_writer_disable(3) has been invoked, these functions will abort(3) if called.

RETURN VALUES
These functions return 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.
