TT_FD(3)

okay so bestie, welcome to the tt_fd page from the library call section — it's literally about returning a file descriptor, no cap. 💅✨

🎀 NAME 🎀

tt_fd — return a file descriptor

✨ SYNOPSIS ✨

#include &<Tt/tt_c.h>
int tt_fd(void)

💖 DESCRIPTION 💖

So the tt_fd function returns a file descriptor. This returned file descriptor alerts the process that a message has arrived for the default procid in the default session. 👑

File descriptors are either active or inactive. When the file descriptor becomes active, the process must call tt_message_receive(3) to receive the message. like, mandatory bestie, no skipping. 🫶

🌈 RETURN VALUE 🌈

Upon successful completion, tt_fd returns the file descriptor for the current procid. The application can use tt_int_error(3) to extract one of the following Tt_status values from the returned integer:

• TT_OK — the operation completed successfully. slay. ✅
• TT_ERR_NOMP — the ttsession(1) process is not running and the ToolTalk service cannot restart it. 😭
• TT_ERR_PROCID — the current default process identifier is out of date or invalid. 💀
• TT_ERR_SESSION — the specified ToolTalk session is out of date or invalid. 🙈

🦋 APPLICATION USAGE 🦋

The application must have a separate file descriptor for each procid. To get an associated file descriptor, the application should use tt_fd each time it calls tt_open(3). that's the whole assignment, bestie. 🎀
