KXML_POPALL(3) Library Functions Manual KXML_POPALL(3)

NAME

kxml_popallclose all element scopes 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_popall(struct kxmlreq *req);

DESCRIPTION

Closes all open element scopes of req, initialised with kxml_open(3). Scopes are opened with kxml_push(3) or kxml_pushattrs(3). If there are no open scopes, this does nothing.

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). Indicates 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 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_push(&req, 1); /* bar */ 
kxml_push(&req, 2); /* baz */ 
kxml_popall(&req); 
kxml_close(&req);
