NAME

—
open object scope for
kcgijson
LIBRARY
library “libkcgijson”
SYNOPSIS
#include
<sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>
#include <kcgijson.h>
enum kcgi_err
kjson_obj_close
(struct kjsonreq
*req);
DESCRIPTION
Closes an object scope created with kjson_obj_open(3) or kjson_objp_open(3) in a context req initialised with khtml_open(3). It is an error to close a non-object 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 object.
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_putstringp(&req, "data", "shbar"); kjson_obj_close(&req); /* foo */ kjson_objp_open(&req, "bar"); kjson_putstringp(&req, "data", "xyzzy"); kjson_obj_close(&req); /* bar */ kjson_close(&req);
