KHTML_ELEM(3) Library Functions Manual KHTML_ELEM(3) NAME khtml_elem -- open an element scope for kcgihtml LIBRARY library "libkcgihtml" SYNOPSIS #include <sys/types.h> #include <stdarg.h> #include <stdint.h> #include <kcgi.h> #include <kcgihtml.h> enum kcgi_err khtml_elem(struct khtmlreq *req, enum kelem elem); DESCRIPTION Open a new scope of element elem on the current element stack of req, initialised with khtml_open(3). Scopes are closed with khtml_closeelem(3), khtml_closeto(3). or khtml_close(3). If elem is a "void" element (self-closing, like KELEM_LINK) or KELEM_DOCTYPE, the scope is immediately closed so no new scope is opened. RETURN VALUES Returns an enum kcgi_err indicating the error state. KCGI_OK Success (not an error). KCGI_ENOMEM Internal memory allocation failure, including reaching the maximum number of possible HTML scopes. 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. 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_HEAD); khtml_elem(&req, KELEM_TITLE); khtml_puts(&req, "Hello, world."); khtml_close(&req); SEE ALSO kcgihtml(3) STANDARDS The referenced HTML5 standard is HTML5.2: https://www.w3.org/TR/html52.
