KHTML_PUTS(3) Library Functions Manual KHTML_PUTS(3)
NAME
khtml_puts — put string content for kcgihtml
LIBRARY
library “libkcgihtml”
SYNOPSIS
#include <sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>
#include <kcgihtml.h>
enum kcgi_err
khtml_puts(struct khtmlreq *req, const char *cp);
DESCRIPTION
Writes a NUL-terminated string cp to a context req initialised with khtml_open(3). If cp is NULL, does nothing and returns success. All of the content is HTML escaped, for example, the left-angle bracket "<" is rendered as "<". It does not append a newline like puts(3).
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.
EXAMPLES
The following outputs a simple HTML 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_TEXT_HTML]);
khttp_body(r);
khtml_open(&req, r, 0);
khtml_elem(&req, KELEM_DOCTYPE);
khtml_elem(&req, KELEM_HTML);
khtml_elem(&req, KELEM_BODY);
khtml_elem(&req, KELEM_P);
khtml_puts(&req, "Hello, world.");
khtml_close(&req);
