Parallel BZIP2 1.0.4 (Default branch)
12-22-2008
PBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 1.0.2 or newer (ie: anything compressed with PBZIP2 can be decompressed with bzip2).License: BSD License (original)Changes:|

PARPORT_REGISTER_POR(9) Parallel Port Devices PARPORT_REGISTER_POR(9) NAME
parport_register_port - register a parallel port SYNOPSIS
struct parport * parport_register_port(unsigned long base, int irq, int dma, struct parport_operations * ops); ARGUMENTS
base base I/O address irq IRQ line dma DMA channel ops pointer to the port driver's port operations structure DESCRIPTION
When a parallel port (lowlevel) driver finds a port that should be made available to parallel port device drivers, it should call parport_register_port. The base, irq, and dma parameters are for the convenience of port drivers, and for ports where they aren't meaningful needn't be set to anything special. They can be altered afterwards by adjusting the relevant members of the parport structure that is returned and represents the port. They should not be tampered with after calling parport_announce_port, however. If there are parallel port device drivers in the system that have registered themselves using parport_register_driver, they are not told about the port at this time; that is done by parport_announce_port. The ops structure is allocated by the caller, and must not be deallocated before calling parport_remove_port. If there is no memory to allocate a new parport structure, this function will return NULL. COPYRIGHT
