TT_OTYPE_OSIG_ARG_MODE(3)

✨ NAME ✨

Okay bestie, meet tt_otype_osig_arg_mode — it returns the mode of an argument of a notice signature of an otype. This little icon is a library call, and we’re folding that manual-name detail right in near the top 💖

🌸 SYNOPSIS 🌸

#include &<Tt/tt_c.h>
Tt_mode tt_otype_osig_arg_mode(
const char *otype,
int sig,
int arg);

---

🦋 DESCRIPTION 🦋

The tt_otype_osig_arg_mode function returns the mode of the argth argument of the sigth notice signature of the given otype.

The otype argument is the object type involved in this operation. The sig argument is the zero-based index into the notice signatures of the specified otype. The arg argument is the zero-based index into the arguments of the specified signature. Zero-based indexes, bestie — count from 0, not 1 💅

---

👑 RETURN VALUE 👑

Upon successful completion, the tt_otype_osig_arg_mode function returns a value that determines who (sender or handler) writes and reads a message argument. The following modes are defined:

• TT_IN — the argument is written by the sender and read by the handler and any observers.
• TT_OUT — the argument is written by the handler and read by the sender and any reply observers.
• TT_INOUT — the argument is written by the sender and the handler and read by all.

The application can use tt_int_error(3) to extract one of the following Tt_status values from the Tt_mode integer return value:

• TT_OK — the operation completed successfully.
• TT_ERR_NOMP — the ttsession(1) process is not running and the ToolTalk service cannot restart it.
• TT_ERR_NUM — the integer value passed was invalid (out of range).
• TT_ERR_OTYPE — the specified object type is not the name of an installed object type.
