NAME

kxml_puts — put string content for kcgixml

LIBRARY

library “libkcgixml”

SYNOPSIS

#include <sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>
#include <kcgixml.h>

enum kcgi_err
kxml_puts(struct kxmlreq *req, const char *cp);

DESCRIPTION

Writes a NUL-terminated string cp to a context req initialised with kxml_open(3). If cp is NULL, does nothing and returns success. All of the content is XML escaped. It does not append a newline like puts(3).

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);
