KXML_PUTC(3)

NAME
kxml_putc - put character content for kcgixml

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);
