KXML_POP(3) Library Functions Manual KXML_POP(3) NAME kxml_pop -- close an element scope for kcgixml LIBRARY library "libkcgixml" SYNOPSIS #include <sys/types.h> #include <stdarg.h> #include <stdint.h> #include <kcgi.h> #include <kcgihxml.h> enum kcgi_err kxml_pop(struct kxmlreq *req); DESCRIPTION Closes a single element scope of req, initialised with kxml_open(3). Scopes are opened with kxml_push(3) or kxml_pushattrs(3). It is an error to pop from an empty scope stack. 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. KCGI_WRITER There are no open scopes to pop. EXAMPLES The following outputs a simple XML page. It assumes r is a struct kreq pointer. For brevity, it does not do any error checking. const char *const elems[] = { "foo", "bar", "baz" }; khttp_head(r, kresps[KRESP_STATUS], "%s", khttps[KHTTP_200]); khttp_head(r, kresps[KRESP_CONTENT_TYPE], "%s", kmimetypes[KMIME_TEXT_XML]); khttp_body(r); kxml_open(&req, r, elems, 3); kxml_push(&req, 0); /* foo */ kxml_puts(&req, "Hello, world"); kxml_pop(&req); kxml_push(&req, 1, "baz", "xyzzy"); /* bar */ kxml_puts(&req, "Hello, world"); kxml_pop(&req); kxml_close(&req); SEE ALSO kcgixml(3) AUTHORS Written by Kristaps Dzonsons <kristaps@bsd.lv>.
