CVS commit: src/usr.bin/sort

[David Laight <dsl%netbsd.org@localhost>]

Module Name:    src
Committed By:   dsl
Date:           Sat Sep 26 21:16:55 UTC 2009

Modified Files:
        src/usr.bin/sort: files.c fsort.c fsort.h msort.c sort.c sort.h tmp.c

Log Message:
Move all the fopen() calls out of the record read routines into the callers.
Split the merge sort so that fsort() can pass the 'FILE *' of the temporary
files to be merged into the merge code.
Don't rely on realloc() not moving the end address of a buffer!
Rework merge sort so that it sorts pointers to 'struct mfile' and only
copies about sort record descriptors.
No functional change intended.
