To replace "\" with "/" in a string using FrameMaker API

Question

How to replace "\folder1\folder2\folder3" with "folder1/folder2/folder3" using framemaker API ?

Answer 1

Hi Asha,
Here is a function that I use for substring replacement, using all FDK library functions. If you use standard C libraries instead, you could probably reduce this to a line or two.
To use it, you would send something like:
path = F_StrCopyString("\\folder1\\folder2\\folder3");
strReplace(path, "\\", "/", False);
There might be better ways to do this. I'm not really that much of a programmer.
