KJSON_STRING_WRITE(3)	     Library Functions Manual	   KJSON_STRING_WRITE(3)

NAME
     kjson_string_write -- put content data 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_string_write(const char *buf, size_t sz, void *arg);

DESCRIPTION
     Write  binary  data  buf  of  length sz into a string scope opened with kj-
     son_string_open(3) or kjson_stringp_open(3) to  a	context  arg,  a  struct
     kjsonreq  initialised  with  khtml_open(3) and passed as an opaque pointer.
     If buf is NULL or sz is zero, do nothing and return KCGI_OK.

     All characters are JSON escaped so that content cannot prematurely end  its
     context.

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_string_open(&req);
	   kjson_string_write("hello", 5, &req);
	   kjson_close(&req);
