KJSON_STRING_CLOSE(3) Library Functions Manual KJSON_STRING_CLOSE(3)
NAME
kjson_string_close — open string 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_string_close(struct kjsonreq *req);
DESCRIPTION
Closes an string scope created with kjson_string_open(3) or kjson_stringp_open(3) in a context req initialised with khtml_open(3). It is an error to close a non-string 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 a string.
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_string_open(&req);
kjson_string_puts(&req, "Hello, ");
kjson_string_puts(&req, "world.");
kjson_string_close(&req);
kjson_close(&req);
