KJSON_PUTINT(3) Library Functions Manual KJSON_PUTINT(3) NAME kjson_putint, kjson_putintp, kjson_putintstr, kjson_putintstrp, kjson_string_putint -- put integer content 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_putint(struct kjsonreq *req, int64_t v); enum kcgi_err kjson_putintp(struct kjsonreq *req, const char *name, int64_t v); enum kcgi_err kjson_string_putint(struct kjsonreq *req, int64_t v); enum kcgi_err kjson_putintstr(struct kjsonreq *r, int64_t v); enum kcgi_err kjson_putintstrp(struct kjsonreq *r, const char *name, int64_t v); DESCRIPTION Write a 64-bit integer v to a context req initialised with khtml_open(3). This formats the value as [-]?[0-9]+. The kjson_putint() and kjson_putintstr() forms are for array scopes, kjson_putintp() and kjson_putintstrp() for objects, and kjson_string_putint() for open strings. Since JavaScript is limited to 53 bits, it's possible that integers may be truncated with kjson_putint() and family. The alternative forms, kjson_putintstr() and kjson_putintstrp(), emit the value within a string. This allows the JavaScript to parse the integer and handle overflow and underflow explicitly. Passing a NULL value to name for kjson_putintp() or kjson_putintstrp() is equivalent to calling kjson_putint() or kjson_putintstr(), respec- tively. 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. KCGI_WRITER The incorrect form was used for the current scope, for example, an array-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_putintp(&req, "bar", 12345); kjson_arrayp_open(&req, "baz"); kjson_putint(&req, 1)); /* 1 */ kjson_putintstr(&req, 1)); /* "1" */ kjson_close(&req); SEE ALSO kcgijson(3) AUTHORS Written by Kristaps Dzonsons <kristaps@bsd.lv>.
