KCGI_BUF_PRINTF(3) Library Functions Manual KCGI_BUF_PRINTF(3) NAME kcgi_buf_printf -- put variable 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 *fmt, ...); DESCRIPTION Appends output according to the given fmt to a buffer buf. The format is as for printf(3). Buffers must be initialised to zero with memset(3) prior to first use. 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. EXAMPLES 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_printf(&buf, "number %d", 1); puts(buf.buf); /* Emits "number 1" */ free(buf.buf); SEE ALSO kcgi_buf_putc(3), kcgi_buf_puts(3), kcgi_buf_write(3) AUTHORS Written by Kristaps Dzonsons <kristaps@bsd.lv>.
