.SH DESCRIPTION
.sp
.LP
The \fBdat_set_consumer_context()\fR function associates a Consumer context with the specified \fIdat_handle\fR. The \fIdat_handle\fR can be one of the following handle types: \fBDAT_IA_HANDLE\fR, \fBDAT_EP_HANDLE\fR, \fBDAT_EVD_HANDLE\fR, \fBDAT_CR_HANDLE\fR, \fBDAT_RSP_HANDLE\fR, \fBDAT_PSP_HANDLE\fR, \fBDAT_PZ_HANDLE\fR, \fBDAT_LMR_HANDLE\fR, \fBDAT_RMR_HANDLE\fR, or \fBDAT_CNO_HANDLE\fR.
.sp
.LP
Only a single Consumer context is provided for any \fIdat_handle\fR. If there is a previous Consumer context associated with the specified handle, the new context replaces the old one. The Consumer can disassociate the existing context by providing a NULL pointer for the \fIcontext\fR. The Provider makes no assumptions about the contents of \fIcontext\fR; no check is made on its value. Furthermore, the Provider makes no attempt to provide any synchronization for access or modification of the \fIcontext\fR.
