Escape Character in directory path
Hi
I need to pass a path to FindFirstFile() that is specified by the user,
problem is that all \ characters need to be prefixed with another \, what is
the easiest way to do this short of scanning the entire string and replacing
a \ with \\.
Kind Regards

This is a Windows function, not a standard C++ function. Discussion of
platform-specific libraries should generally be done on other groups.

No they don't. That is something you need to do in source code, not in
memory.

Tell the user to do it. ;-)

Actually, you don't need to do a thing. The string containing
\ characters is just fine.
The problem you may be thinking about is with *literal* strings
in your program. It's not the fact that the string contains \
characters: the problem is precisely that the string DOES NOT
contain the \ characters that it should:
"c:\temp\total.txt"
Does not contain a single \ character -- it does contain two
TAB characters, though. But if the user enters the above
string, then your string variable will indeed contain the
two \ characters and everything will work fine.
BTW, it is normally recommended to use / for paths -- either
on Unix/Linux or on DOS/Windows, it works. This, of course,
applies to *literal strings* in your program containing
paths. For instance:
"c:/temp/total.txt"
will work fine.
HTH,
Carlos
