7.79. CUmemDecompressParams

Defined in cuda.h

struct CUmemDecompressParams

Structure describing the parameters that compose a single decompression operation.

Public Members

size_t srcNumBytes: The number of bytes to be read and decompressed from ::CUmemDecompressParams_st.src.

size_t dstNumBytes

The number of bytes that the decompression operation will be expected to write to ::CUmemDecompressParams_st.dst.

This value is optional; if present, it may be used by the CUDA driver as a heuristic for scheduling the individual decompression operations.

cuuint32_t *dstActBytes: After the decompression operation has completed, the actual number of bytes written to CUmemDecompressParams.dst will be recorded as a 32-bit unsigned integer in the memory at this address.

const void *src: Pointer to a buffer of at least ::CUmemDecompressParams_st.srcNumBytes compressed bytes.

void *dst

Pointer to a buffer where the decompressed data will be written.

The number of bytes written to this location will be recorded in the memory pointed to by ::CUmemDecompressParams_st.dstActBytes
