Untangle #ifdefs in the write-end of things by giving each arch its

own file and own copy of WriteDisk() to do things in. This should have happened years ago, instead of adding #ifdefs all over the place.

Swing the weed-whacker around libdisk:

Constify some things. Staticize some things. Remove some unused things. Prototype some things. Don't install a gazillion man-pages links. Drop support for ON-TRACK disk-manager.

Modernize my email address.

Add __FBSDID()s to libdisk

+ add u_long sector_size to struct disk (documented in libdisk.3)

2001-05-13T20:08:54Z

+ make Open_Disk sense the sector size by trying 512, 1024 and 2048 in this order. This makes the kernel note that dscheck(cd1): bio_bcount 512 is not on a sector boundary (ssize 2048) dscheck(cd1): bio_bcount 1024 is not on a sector boundary (ssize 2048) if 2048 is the sector size. If this worries anyone: the message is from /usr/src/sys/kern/subr_diskslice.c and shutups are to be placed there. + Have read_block and write_block use an additional parameter, the sector size. + replace all barfout calls with return NULL, 0, __LINE__, etc. Note that this does NOT emit diagnostics. More often than not, you don't want library functions to scribble on stderr -- it may not even be available. The right thing is to propagate the error condition to upper management. The app should take care of errors. + use d1->sector_size instead of 512 in various places. I've left many places untouched, especially those writing MBRs. I simply added another arg hardcoded as 512. This is because I would not know what I'm doing... I felt this approach would be reasonably backward compatible and not introduce any new bugs in critical software. Famous last words. Messing with MBRs might soon put me in the same screwup meister category as, uh, never mind. :-) + bump the max no of disks from 20 to 32 (due to PR 24503).

Add spaces around operators.

It's OK, the Project and afford them now -- they aren't as expensive as they used to be.

Libraries should _never_ call exit() themselves (or its alternate spelling

2001-03-18T21:30:11Z

`err()'). libdisk does! and additionally libdisk gets confused on Alpha disks with foreign disklabels, throws up its hands and exits. This is the cause of the "going no where without my init" install bug on the Alpha. So now on the Alpha, rather than call err(), we print the error string and continue processing. Submitted by: jkh
