DESCRIPTION
The
tt_pattern_barg_add function
adds an argument with a value that contains embedded nulls to a pattern.
The
m argument is the opaque handle for the pattern involved in this operation.
The
n argument specifies who
(sender, handler, observers) 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
vtype argument describes the type of argument data being added.
Type
ALL matches any argument value type.
The ToolTalk service treats the value as an opaque byte string.
To pass structured data, the application and the receiving application
must encode and decode these unique values.
The most common method to use is XDR.
The
value argument is the value to be added.
NULL matches any value.
The
len argument is the length of the value in bytes.
RETURN VALUE
Upon successful completion, the
tt_pattern_barg_add function returns the status of the operation as one of the following
Tt_status values:
TT_OK
The operation completed successfully.
TT_ERR_NOMP
The
&cdeman.ttsession; process is not running and the ToolTalk service cannot restart it.
TT_ERR_POINTER
The pointer passed does not point to an object of
the correct type for this operation.
