🎀 NAME 🎀

kcgi_writer_putc — write into a writer

📚 LIBRARY 📚

library “libkcgi” — that's the library, no cap.

✨ SYNOPSIS ✨

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

enum kcgi_err
kcgi_writer_putc(struct kcgi_writer *writer, char c);

🦋 DESCRIPTION 🦋

The kcgi_writer_putc() function writes character c to a writer channel opened by kcgi_writer_get(3). and yes, it allows writing after kcgi_writer_disable(3), unlike khttp_write(3) — iykyk, that's the whole flex. kcgi_writer_putc() is backed by kcgi_writer_write(3).

💖 RETURN VALUES 💖

It returns an enum kcgi_err indicating the error state. vibe check on the possible moods:

• KCGI_OK — Success (not an error). periodt.
• KCGI_ENOMEM — Internal memory allocation failure. ugh, the memory said no.
• 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. not the vibe.
