• Russell E. Jones 1991-03 Changes for SiliconGraphics IRIS-4D/25 SiliconGraphics 3.3 FORTRAN 77

To unpack a series of bytes into a target array. Each unpacked byte is right-justified in its target word, and the remainder of the word is zero-filled.

Parameters

[in]	IPACKD	The word or array containing the packed bytes.
[out]	IUNPKD	The array which will contain the unpacked bytes.
[in]	NOFF	The initial number of bits to skip, left to right, in 'IPACKD' in order to locate the first byte to unpack.
[in]	NBITS	Number of bits in the byte to be unpacked. Maximum of 64 bits on 64 bit machine, 32 bits on 32 bit machine.
[in]	ISKIP	The number of bits to skip between each byte in 'IPACKD' in order to locate the next byte to be unpacked.
[in]	ITER	The number of bytes to be unpacked.
