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 argu-
ment is the zero-based index into the arguments of the
specified signature.
RETURN VALUE

by the sender and any reply observers.
TT_INOUT

the following Tt_status values from the Tt_mode integer
return value:
