NAME
khttp_putc — put character content for kcgi
LIBRARY
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);
DESCRIPTION
Writes a character c (converted to an unsigned char) to a kcgi(3) context req as allocated with khttp_parse(3) or khttp_fcgi_parse(3). It should only be called after khttp_body(3).
If kcgi_writer_disable(3) has been previously invoked, this function will abort(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.
