KJSON_OPEN(3) Library Functions Manual KJSON_OPEN(3) NAME kjson_open -- open kcgijson context LIBRARY library "libkcgijson" SYNOPSIS #include <sys/types.h> #include <stdarg.h> #include <stdint.h> #include <kcgi.h> #include <kcgijson.h> enum kcgi_err kjson_open(struct kjsonreq *req, struct kreq *r); DESCRIPTION Zeroes and initialises a new context req with the underlying kcgi(3) context r as allocated with khttp_parse(3) or khttp_fcgi_parse(3). It should only be called after khttp_body(3). The scope open after initialisation is the "root" scope, which accepts similar content as arrays such as kjson_putstring(3) instead of kjson_putstringp(3). If kcgi_writer_disable(3) has been called, the process will be killed with an uncatchable signal. 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 connec- tions, 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). In- dicates 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 JSON page. 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_putstringp(&req, "foo", "bar"); kjson_close(&req); SEE ALSO kcgijson(3) AUTHORS Written by Kristaps Dzonsons <kristaps@bsd.lv>.
