2020-04-24Cygwin: raw disk I/O: lock floppys as wellCorinna Vinschen1-2/+2
The workaround to access the full disk required since Vista and described in http://support.microsoft.com/kb/942448 (NOT ACCESSIBLE at the time of writing this commit message) is required on floppy drives as well. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2020-04-24Cygwin: raw disk I/O: Fix return value in error caseCorinna Vinschen1-3/+4
The cast to generate the return value uses a DWORD variable as test and set value. The error case is the constant -1. Given the type of the other half of the conditioal expression, -1 is cast to DWORD as well. On 64 bit, this results in the error case returning a 32 bit -1 value which is equivalent to (ssize_t) 4294967295 rather than (ssize_t) -1. Add a fixing cast.

2017-12-19cygwin: block devices: fix file offset after short writesnewlib-snapshot-20171222Corinna Vinschen1-2/+10
When reading/writing block devices, Cygwin emulates Linux, providing a byte-exact file position, albeit the underlying device drivers don't. Unfortunately this only worked correctly for reading. The raw_write method failed to revalidate the buffer after the read-modify-write cycle in case len is not a multiple of the sector length. This in turn resulted in lseek reporting a wrong file pointer. Also, fix a condition for invalidating the buffer after writing from a remaining read buffer.

2016-06-24Fix major device check when locking partitionsCorinna Vinschen1-10/+7
The change introduced in commit b2867a6 contains a faulty check for the major device number in fhandler_dev_floppy::lock_partition. Fix this. Also fix comments. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2016-06-23Handle up to 63 partitions per driveCorinna Vinschen1-2/+3
Revamp device parsing code. Introducing support for more partitions into the shilka-generated parser has the unfortunate side-effect of raising the size of the DLL by almost 2 Megs. Therefore we split out the handling for /dev/sdXY devices into a tiny bit of hand-written code. While at it, remove some unused cruft from devices.* and generally clean up the device class to provide access methods instead of direct access to members.
