Thread: [Dev-C++] Backslashes in Windows path and escaping

Hello,

I need to put in a char const a full Windows path to a file.
I.e. i did it as follows

fopen ("..\path\filename", "r");

It puts down some warnings about unknown escape characters.
So I rewrite it to :

fopen ("..\\path\\filename", "r");

Is this correct?

Thank you

Yes, that is correct.

The '\' character is an escape character, used to make characters that
are special (eg '\'' get's me a single quote mark).

By escaping the escape character you get a single backwhack.

The "native" way is the one you selected, i.e. dual backslash.

However, the "compatible" whay to do it is to use a single forward slash
instead, i.e. "../path/filename".

The C RTL on Windows will automagically translate the forward slash into a
backward slash before sending the string to the OS.
