KCGI_BUF_PUTC(3)

KCGI_BUF_PUTC(3) 🎀

Okay so bestie, this is the Library Functions Manual page for KCGI_BUF_PUTC(3), and the library is library “libkcgi”. Quick heads-up: the NAME section literally says kcgi_buf_puts, not kcgi_buf_putc — that’s what the page says, so we’re keeping it, iykyk. 💅

💖 NAME 💖

kcgi_buf_puts — put a character 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_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. Periodt — zero it first, bestie, no cap. ✨

🔥 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 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_putc(&buf, 'f');
kcgi_buf_putc(&buf, 'o');
kcgi_buf_putc(&buf, 'o');
puts(buf.buf); /* Emits "foo" */
free(buf.buf);
