win32: Unix-like support for volume mounts

2026-06-15T11:42:54+00:00

Add code to distinguish between volume mount points and junctions. Volume mount points are to be treated like directries while junctions are like symlinks. Update the 'mntent' functions to scan drive letters first, then volume names and their associated mount points. By default the filesystem is returned as a drive letter, if possible, though the volume name is also returned. The function 'find_mount_point()' has been updated to use the new 'mntent' routines. Adds 772-803 bytes. Signed-off-by: Ron Yorston

find_mount_point: code shrink

2021-08-12T12:27:46+00:00

Use xrealloc_getcwd_or_warn() instead of a hand-rolled WIN32 equivalent. Saves 84 bytes.

ash, libbb: don't affect POSIX build

2021-07-13T09:43:14+00:00

Tweak code to avoid contamination of the POSIX build. There weren't any adverse effects, but better safe than sorry.

win32: changes to mntent implementation

2021-06-27T13:05:33+00:00

Make the structure returned by getmntent(3) static so it persists after endmntent(3) closes the stream. No current caller in the WIN32 port needs this functionality but it's good to match the documented behaviour. Populate more fields of the mntent structure in find_mount_point(). This is required to support the df -t and -T flags recently added upstream. The static structures used here are allocated on demand. Separate static structures are used in each case because df iterates through mounts calling statfs(2) on each and the WIN32 implementation of statfs(2) calls find_mount_point().
