.SH "Detailed Description"
.PP 
External memory handle descriptor 
.SH "Field Documentation"
.PP 
.SS "int \fBCUDA_EXTERNAL_MEMORY_HANDLE_DESC::fd\fP"
.PP

.SS "void* \fBCUDA_EXTERNAL_MEMORY_HANDLE_DESC::handle\fP"
.PP
Valid NT handle. Must be NULL if 'name' is non-NULL 
.SS "unsigned long long \fBCUDA_EXTERNAL_MEMORY_HANDLE_DESC::size\fP"
.PP

.SS "\fBCUexternalMemoryHandleType\fP \fBCUDA_EXTERNAL_MEMORY_HANDLE_DESC::type\fP"
.PP
Type of the handle 
.SS "struct { ... }   \fBCUDA_EXTERNAL_MEMORY_HANDLE_DESC::win32\fP"
.PP
Win32 handle referencing the semaphore object. Valid when type is one of the following:
.IP "\(bu" 2
\fBCU_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32\fP
.IP "\(bu" 2
\fBCU_EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_KMT\fP
.IP "\(bu" 2
\fBCU_EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP\fP
.IP "\(bu" 2
