KXML_PUTC(3) Library Functions Manual KXML_PUTC(3)
NAME
kxml_putc — put character 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_putc(struct kxmlreq *req, char c);
DESCRIPTION
Writes a NUL-terminated string cp to a context req initialised with kxml_open(3). The character is XML escaped.
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_putc(&req, ’H’);
kxml_putc(&req, ’i’);
kxml_putc(&req, ’!’);
kxml_close(&req);
