Yes, Max is right. I hadn't thought about the difference between a
"native win32" environment vs. "from a DOS prompt on a system that has
Cygwin in its path" (I rarely, if ever, run in a "native win32"
I don't understand why we don't just get MSFT to ship cygwin1.dll...
One last point: not all flavours of Windows that are targetted for
SWISH-E support the "/" vs. "\" (e.g. Win95/98). At least, I don't
think they support it...but again, its been a long while since I've sat
in front of such a box.
From the MSDN:
File Name Conventions
Although each file system can have specific rules about the formation of
individual components in a directory or file name, all file systems follow the
same general conventions: a base file name and an optional extension, separated
by a period. For example, the MS-DOS FAT file system supports 8 characters for
the base file name and 3 characters for the extension. This is known as an 8.3
file name. The FAT file system and NTFS support file names that can be up to 255
characters long. This is known as a long file name. To get an MS-DOS file name
given a long file name, use the GetShortPathName function. To get the full path
of a file, use the GetFullPathName function.
Both file systems use the backslash (\) character to separate directory names
and the file name when forming a path.
General rules for applications creating names for directories and files or
processing names supplied by the user include the following:
Use any character in the current code page for a name, but do not use a path
separator, a character in the range 0 through 31, or any character explicitly
disallowed by the file system. A name can contain characters in the extended
character set (128–255).
Use the backslash (\), the forward slash (/), or both to separate components in
a path. No other character is acceptable as a path separator. Note that UNC
names must adhere to the following format: \\server\share.
So there may be a need to backslashify the UNC portion of a path. Other
than that, forward slashes are fine.
