KHTTP_PRINTF(3) Library Functions Manual KHTTP_PRINTF(3) NAME khttp_printf -- put variable content for kcgi LIBRARY library "libkcgi" SYNOPSIS #include <sys/types.h> #include <stdarg.h> #include <stdint.h> #include <kcgi.h> enum kcgi_err khttp_printf(struct kreq *req, const char *fmt, ...); DESCRIPTION Writes output according to the given fmt to a kcgi(3) context req as allocated with khttp_parse(3) or khttp_fcgi_parse(3). The format is as for printf(3). It should only be called after khttp_body(3). If fmt is NULL, it does nothing and returns success. 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 connec- tions, 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). In- dicates 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. SEE ALSO kcgi(3), kcgi_writer_disable(3), khttp_body(3), khttp_parse(3) AUTHORS Written by Kristaps Dzonsons <kristaps@bsd.lv>.
