KCGI_BUF_PUTC(3) Library Functions Manual KCGI_BUF_PUTC(3) NAME kcgi_buf_puts -- put a character into a kcgi buffer LIBRARY libkcgi SYNOPSIS #include <sys/types.h> #include <stdarg.h> #include <stdint.h> #include <kcgi.h> enum kcgi_err kcgi_buf_putc(struct kcgi_buf *buf, char c); DESCRIPTION Appends a character c to a buffer buf. 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 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. 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_putc(&buf, 'f'); kcgi_buf_putc(&buf, 'o'); kcgi_buf_putc(&buf, 'o'); puts(buf.buf); /* Emits "foo" */ free(buf.buf); SEE ALSO kcgi_buf_printf(3), kcgi_buf_putc(3), kcgi_buf_write(3) AUTHORS Written by Kristaps Dzonsons <kristaps@bsd.lv>.
