Service:File System Services (64-Bit)
Defined In:zParams.h

Syntax

 struct                            /* zGET_BLOCK_SIZE */
 {
    LONG   size;
    LONG   sizeShift;
 } blockSize;

Fields

size

Specifies the logical size (which is always a power of 2 and a multiple of the underlying storage pool allocation unit size) of the file object’s basical allocation blocks.

sizeShift

Specifies the shift factor that is used in working with the size of the block. If size is 2 raised to the nth power, the value of sizeShift is n. If 1 is shifted left by this value, the resultant value is the same value as size.
