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

kcgi_buf_puts
put string content into a kcgi buffer

library “libkcgi”

#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);

Appends a NUL-terminated string cp to a buffer buf. Buffers must be initialised to zero with memset(3) prior to first use. Does nothing if cp is NULL. It does not append a newline like puts(3).

Returns an enum kcgi_err indicating the error state.
Success (not an error).
Internal memory allocation failure.
The output connection has been terminated. For FastCGI connections, the current connection should be released with khttp_free(3) and parse loop reentered.
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.
Internal system error writing to the output stream.

The following creates a simple NUL-terminated buffer and outputs its contents. 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);

kcgi_buf_printf(3), kcgi_buf_putc(3), kcgi_buf_write(3)
