NAME

tt_message_abstainer — return offer's nth abstaining procid

SYNOPSIS

#include &<Tt/tt_c.h>
char *tt_message_abstainer(
Tt_message m,
int n);

DESCRIPTION

The tt_message_abstainer function returns the procid of the nth abstainer of the specified message.

The m argument is the opaque handle for the message involved in this operation. The n argument is the number of the abstainer to be returned. The first abstainer is numbered zero.

RETURN VALUE

Upon successful completion, the tt_message_abstainer function returns the procid of the nth abstainer. The application can use tt_ptr_error to extract one of the following Tt_status values from the returned pointer:

TT_OK

The operation completed successfully.

TT_ERR_PROCID

There is no valid default procid, perhaps because tt_open has not yet been called.

TT_ERR_NUM

The integer value passed was invalid (out of range).

TT_ERR_STATE

The specified message is not in state TT_RETURNED. Since only TT_OFFERs can be in state TT_RETURNED, this status will be returned if the specified message is a TT_NOTICE or a TT_REQUEST.

TT_ERR_POINTER

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

APPLICATION USAGE

The application can use tt_free to free any data stored in the address returned by the ToolTalk API.
