\\brief deprecated device management functions of the low-level CUDA driver API (\fBcuda.h\fP)
.PP
This section describes the device management functions of the low-level CUDA driver application programming interface.

\fBDeprecated\fP
.RS 4
.RE
.PP
This function was deprecated as of CUDA 5.0 and its functionality superceded by \fBcuDeviceGetAttribute()\fP.
.PP
Returns in \fC*major\fP and \fC*minor\fP the major and minor revision numbers that define the compute capability of the device \fCdev\fP.
.PP
\fBParameters:\fP
.RS 4
\fImajor\fP - Major revision number 
.br
\fIminor\fP - Minor revision number 
.br
\fIdev\fP - Device handle

.PP
This function was deprecated as of CUDA 5.0 and replaced by \fBcuDeviceGetAttribute()\fP.
.PP
Returns in \fC*prop\fP the properties of device \fCdev\fP. The \fBCUdevprop\fP structure is defined as:
.PP
.PP
.nf
     typedef struct CUdevprop_st {
     int maxThreadsPerBlock;
     int maxThreadsDim[3];
     int maxGridSize[3];
     int sharedMemPerBlock;
     int totalConstantMemory;
     int SIMDWidth;
     int memPitch;
     int regsPerBlock;
     int clockRate;
     int textureAlign
  } CUdevprop;
.fi
.PP
 where:
.PP
.IP "\(bu" 2
maxThreadsPerBlock is the maximum number of threads per block;
.IP "\(bu" 2
maxThreadsDim[3] is the maximum sizes of each dimension of a block;
.IP "\(bu" 2
maxGridSize[3] is the maximum sizes of each dimension of a grid;
.IP "\(bu" 2
sharedMemPerBlock is the total amount of shared memory available per block in bytes;
.IP "\(bu" 2
totalConstantMemory is the total amount of constant memory available on the device in bytes;
.IP "\(bu" 2
SIMDWidth is the warp size;
.IP "\(bu" 2
memPitch is the maximum pitch allowed by the memory copy functions that involve memory regions allocated through \fBcuMemAllocPitch()\fP;
.IP "\(bu" 2
regsPerBlock is the total number of registers available per block;
.IP "\(bu" 2
clockRate is the clock frequency in kilohertz;
.IP "\(bu" 2
textureAlign is the alignment requirement; texture base addresses that are aligned to textureAlign bytes do not need an offset applied to texture fetches.
