KCGI_BUF_PUTS(3)       FreeBSD Library Functions Manual	      KCGI_BUF_PUTS(3)

NAME
     kcgi_buf_puts -- put string content into a	kcgi buffer

LIBRARY
     library "libkcgi"

SYNOPSIS
     #include <sys/types.h>
     #include <stdarg.h>
     #include <stdint.h>
     #include <kcgi.h>

     enum kcgi_err
     kcgi_buf_puts(struct kcgi_buf *buf, const char *cp);

DESCRIPTION
     Appends a NUL-terminated string cp	to a buffer buf.  Buffers must be ini-
     tialised to zero with memset(3) prior to first use.  Does nothing if cp
     is	NULL.  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).	 Indi-
	  cates	that khttp_body(3) did not return with success or was not in-
	  voked.  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 creates a simple NUL-terminated buffer and outputs its con-
     tents.  It	does not perform any error checking.

	   struct kcgi_buf buf;

	   memset(&buf,	0, sizeof(struct kcgi_buf));
	   kcgi_buf_puts(&buf, "Hello, world!");
	   puts(buf.buf); /* Emits "Hello, world!" */
	   free(buf.buf);
