Re: [Patch]: NUL and other special names


I don't how much you want to rely on undocumented features, but ntdll.dll exports a function called RtlIsDosDeviceName_U(). The WINE implementation has the following to say about it:


/*********************************************************************** * RtlIsDosDeviceName_U (NTDLL.@) * * Check if the given DOS path contains a DOS device name. * * Returns the length of the device name in the low word and its * position in the high word (both in bytes, not WCHARs), or 0 if no * device name is found. */ ULONG WINAPI RtlIsDosDeviceName_U( PCWSTR dos_name )




Also, from the patch:


/* COM and LPT must be followed by a single digit */

The code in src/winsup/cygwin/devices.cc would seem to indicate that the number is not limited to a single digit.


Cheers
