KJSON_ARRAY_CLOSE(3)

NAME
kjson_array_close - open array scope for kcgijson

LIBRARY
libkcgijson

SYNOPSIS
#include <sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>
#include <kcgijson.h>
enum kcgi_err
kjson_array_close(struct kjsonreq *req);

DESCRIPTION
Closes an array scope created with kjson_array_open(3) or kjson_arrayp_open(3) in a context req initialised with khtml_open(3). It is an error to close a non-array scope.

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.

KCGI_WRITER
    The current scope is not an array.

EXAMPLES
The following outputs a simple JSON document. It assumes r is a struct kreq pointer. For brevity, it does not do any error checking.

    khttp_head(r, kresps[KRESP_STATUS],
      "%s", khttps[KHTTP_200]);
    khttp_head(r, kresps[KRESP_CONTENT_TYPE],
      "%s", kmimetypes[KMIME_APP_JSON]);
    khttp_body(r);
    kjson_open(&req, r);
    kjson_obj_open(&req);
    kjson_objp_open(&req, "foo");
    kjson_arrayp_open(&req, "data");
    kjson_putstring(&req, "1");
    kjson_putstring(&req, "2");
    kjson_array_close(&req); /* data */
    kjson_putstringp(&req, "xyzzy");
    kjson_close(&req);
