NAME
tt_message_iarg_add - add a new argument to a message object
SYNOPSIS
#include <Tt/tt_c.h>
Tt_status tt_message_iarg_add(Tt_message m,
Tt_mode n,
const char *vtype,
int value);
DESCRIPTION
The tt_message_iarg_add() function adds a new argument to a message
object and sets the value to a given integer.
Add all arguments before the message is sent. To change existing argu-
ment values, the application must use only modes TT_OUT or TT_INOUT.
Adding arguments when replying to a message produces undefined results.
The m argument is the opaque handle for the message 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 han-
dler 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.
The value argument is the value to be added.
RETURN VALUE
Upon successful completion, the tt_message_iarg_add() function returns
the status of the operation as one of the following Tt_status values:
TT_OK The operation completed successfully.
TT_ERR_MODE
The specified Tt_mode is invalid.
TT_ERR_NOMP
The ttsession(1) 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 cor-
rect type for this operation.
