KXML_OPEN(3)

NAME
kxml_open - open kcgixml context

LIBRARY
libkcgixml

SYNOPSIS
#include <sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>
#include <kcgixml.h>
enum kcgi_err
kxml_open(struct kxmlreq *xml, struct kreq *req, const char *const *elems, size_t elemsz);

DESCRIPTION
Zeroes and initialises a new context req with the underlying kcgi(3) context r as allocated with khttp_parse(3) or khttp_fcgi_parse(3). It should only be called after khttp_body(3). The context is initialised with elemsz possible elements having names elems. It is the caller's responsibility that these be valid XML element names.

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). 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_puts(&req, "Hello, world");
    kxml_close(&req);
