NAME

tt_message_arg_ival − retrieve the integer value of a message argument

SYNOPSIS

#include <Tt/tt_c.h>
Tt_status tt_message_arg_ival(Tt_message m,
int n,
int ∗value);

DESCRIPTION

The tt_message_arg_ival() function retrieves the integer value of the nth message argument.

The m argument is the opaque handle for the message involved in this operation.  The n argument is the number of the argument to be retrieved.  The first argument is numbered zero.  The value argument is a pointer to an integer where the ToolTalk service is to store the contents of the argument. 

RETURN VALUE

Upon successful completion, the tt_message_arg_ival() 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 ttsession(1) process is not running and the ToolTalk service cannot restart it. 

TT_ERR_NUM
The integer value passed was invalid (out of range), or, if the value in the message is not yet set (as it would be in observing a request in state TT_SENT and trying to look at the TT_OUT arguments).

TT_ERR_POINTER
The pointer passed does not point to an object of the correct type for this operation.
