KHTML_OPEN(3) Library Functions Manual KHTML_OPEN(3) NAME khtml_open -- open kcgihtml context LIBRARY libkcgihtml SYNOPSIS #include <sys/types.h> #include <stdarg.h> #include <stdint.h> #include <kcgi.h> #include <kcgihtml.h> enum kcgi_err khtml_open(struct khtmlreq *req, struct kreq *r, int opts); DESCRIPTION Zeroes and initialises a new context req with the underlying kcgi(3) con- text r as allocated with khttp_parse(3) or khttp_fcgi_parse(3). It should only be called after khttp_body(3). If opts is set to KHTML_PRETTY, the output is lightly "pretty-printed" with newlines and indentation spaces. By default, output is all on one line. If kcgi_writer_disable(3) has been called, the process will be killed with an uncatchable signal. 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). Indi- cates that khttp_body(3) did not return with success or was not in- voked. For FastCGI connections, the current connection should be re- leased with khttp_free(3) and parse loop reentered. KCGI_SYSTEM Internal system error writing to the output stream. EXAMPLES The following outputs a simple HTML page. It assumes r is a struct kreq pointer. For brevity, it does not do any error checking. khttp_head(r, kresps[KRESP_STATUS], "%s", khttps[KHTTP_200]); khttp_head(r, kresps[KRESP_CONTENT_TYPE], "%s", kmimetypes[KMIME_TEXT_HTML]); khttp_body(r); khtml_open(&req, r, 0); khtml_elem(&req, KELEM_DOCTYPE); khtml_elem(&req, KELEM_HTML); khtml_elem(&req, KELEM_BODY); khtml_puts(&req, "Hello, world"); khtml_close(&req); SEE ALSO kcgihtml(3) STANDARDS The referenced HTML5 standard is HTML5.2.
