KHTML_ELEMAT(3) Library Functions Manual KHTML_ELEMAT(3) NAME khtml_elemat -- get element stack depth of kcgihtml LIBRARY library "libkcgihtml" SYNOPSIS #include <sys/types.h> #include <stdarg.h> #include <stdint.h> #include <kcgi.h> #include <kcgihtml.h> size_t khtml_elemat(const struct khtmlreq *req); DESCRIPTION Gets the current depth of the element stack of req, initialised with khtml_open(3). This is usually used with khtml_closeto(3). If called before opening any element contexts (i.e., a depth of zero), a subsequent khtml_closeto(3) will close all open scopes. 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); pos = khtml_elemat(&req); /* save at html */ khtml_elem(&req, KELEM_HEAD); khtml_elem(&req, KELEM_TITLE); khtml_puts(&req, "Hello, world."); khtml_closeto(&req, pos); /* to html */ khtml_closeelem(&req, 1); /* head */ 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: https://www.w3.org/TR/html52. AUTHORS Written by Kristaps Dzonsons <kristaps@bsd.lv>. CAVEATS If called in a scope that's subsequently closed, then a new scope re- opened and filled in, a corresponding khtml_closeto(3) will unwind the stack to the new scope. In other words this does not identify a save- point: it's merely the scope depth. FreeBSD Ports 14.quarterly $Mdocdate$ KHTML_ELEMAT(3)
