KJSON_PUTBOOL(3) Library Functions Manual KJSON_PUTBOOL(3) NAME kjson_putbool, kjson_putboolp -- put Boolean content 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_putbool(struct kjsonreq *req, int v); enum kcgi_err kjson_putboolp(struct kjsonreq *req, const char *name, int v); DESCRIPTION Write a Boolean v, represented as zero for false and non-zero for true, to a context req initialised with khtml_open(3). The kjson_putbool() form is for array scopes and kjson_putboolp() for ob- jects. Passing a NULL value to name for kjson_putboolp(), is equivalent to calling kjson_putbool(). 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). Indi- cates that khttp_body(3) did not return with success or was not in- voked. For FastCGI connections, the current connection should be re- leased with khttp_free(3) and parse loop reentered. KCGI_SYSTEM Internal system error writing to the output stream. KCGI_WRITER The incorrect form was used for the current scope, for example, an ar- ray-type write within 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_putboolp(&req, "bar", 1); /* true */ kjson_arrayp_open(&req, "baz"); kjson_putbool(&req, 0)); /* false */ kjson_close(&req); SEE ALSO kcgijson(3) AUTHORS Written by Kristaps Dzonsons <kristaps@bsd.lv>.
