tt_message_uid(3)
NAME
tt_message_uid − retrieve the user identifier attribute from a message
SYNOPSIS
#include <Tt/tt_c.h>
uid_t tt_message_uid(Tt_message m);
DESCRIPTION
The tt_message_uid() function retrieves the user identifier attribute from the specified message.
The ToolTalk service automatically sets the user identifier of a message with the user identifier of the process that created the message.
The m argument is the opaque handle for the message involved in this operation.
The application should check the tt_message_uid() and tt_message_gid(3) against the User ID and Group ID of the application receiving the messsage. If the UID and/or GID of the application do not match that of the message then the receiving application should consider failing the message with TT_DESKTOP_EACCES.
RETURN VALUE
Upon successful completion, the tt_message_uid() function returns the user identifier of the message. If the group nobody is returned, the message handle is not valid.
