🦋 KCGI_WRITER_PUTS(3) — write into a writer 🦋

okay bestie, welcome to the KCGI_WRITER_PUTS(3) page from the Library Functions Manual. This little icon lives in the library “libkcgi”, and it's all about pushing a string into a writer. Let's go 💅

💖 NAME 💖

kcgi_writer_puts — write into a writer

📚 LIBRARY 📚

library “libkcgi”

✨ SYNOPSIS ✨

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

enum kcgi_err
kcgi_writer_puts(struct kcgi_writer *writer, const char *cp);

🌸 DESCRIPTION 🌸

The kcgi_writer_puts() function writes the NUL-terminated string cp to a writer channel opened by kcgi_writer_get(3). This one is lowkey special because it allows writing after kcgi_writer_disable(3), unlike khttp_write(3). And kcgi_writer_puts() is backed by kcgi_writer_write(3) — that's the support system, no cap. 🫶

🔥 RETURN VALUES 🔥

Returns an enum kcgi_err indicating the error state. Here's the whole vibe check:

  • KCGI_OK — Success (not an error). Slay. ✨
  • 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. 🧚
