ttdt_file_notice(3) — Subroutines
CDE
NAME
ttdt_file_notice − create and send a standard ToolTalk notice about a file
SYNOPSIS
#include <tttk.h> Tt_message ttdt_file_notice(Tt_message context,
Tttk_op op,
Tt_scope scope,
const char ∗pathname,
int send_and_destroy);
DESCRIPTION
The ttdt_file_notice function is used to create (and optionally send) any of the standard file notices: Created, Deleted, Moved, Reverted, Saved, and Modified.
The ttdt_file_notice function creates a notice with the specified op and scope, and sets its file attribute to pathname. The function adds an unset argument of Tt_mode TT_IN and vtype File to the notice, per the Desktop messaging conventions. If send_and_destroy is True, ttdt_file_notice sends the message and then destroys it; otherwise, it only creates the message.
The context argument describes the environment to use. If context is not zero, messages created by ttdt_file_notice inherit from context all contexts whose slotname begins with the characters ENV_.
RETURN VALUE
If send_and_destroy is False, the ttdt_file_notice function returns the created Tt_message. If send_and_destroy is True, it returns zero; otherwise, it returns an error pointer. The application can use tt_ptr_error(3) to extract one of the following Tt_status values from the returned handle:
TT_DESKTOP_EINVAL
The op argument was TTDT_MOVED and send_and_destroy was True.
TT_ERR_DBAVAIL
The ToolTalk service could not access the ToolTalk database needed for this operation.
TT_ERR_DBEXIST
The ToolTalk service could not access the specified ToolTalk database in the expected place.
TT_ERR_NOMEM
There is insufficient memory available to perform the function.
TT_ERR_NOMP
The ttsession(1) process is not running and the ToolTalk service cannot restart it.
TT_ERR_OVERFLOW
The ToolTalk service has more active messages than it can handle. (The maximum number of active messages is implementation specific, but is at least 2000.)
TT_ERR_POINTER
The pathname argument was NULL or was a ToolTalk error pointer.
TT_ERR_PROCID
The specified process identifier is out of date or invalid.
APPLICATION USAGE
The ttdt_file_event function is a higher-level interface than ttdt_file_notice, and is the preferred way to send all but the Moved notice.
