NAME

khttp_puts — put string content for kcgi

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

enum kcgi_err
khttp_puts(struct kreq *req, const char *cp);

Writes a NUL-terminated string cp to a kcgi(3) context req as allocated with khttp_parse(3) or khttp_fcgi_parse(3). Does nothing if cp is NULL. It should only be called after khttp_body(3). It does not append a newline like puts(3).

If kcgi_writer_disable(3) has been previously invoked, this function will abort(3).

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.
