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

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.

//returns the index of the first change, or -1 if no changes.
IntT ws_StrReplace(StringT *mainString,
                   StringT searchString,
                   StringT replaceString,
                   IntT considerCase)
{
  StringT strBuf,
    returnString,
    appendString;

  IntT i,
    firstIndex = -1;

  //if the search string is empty, there is nothing to do.
  if(F_StrIsEmpty(searchString))
    returnString = F_StrCopyString(*mainString);
 
  else
  {
    //otherwise, initialize the buffer
    returnString = F_StrCopyString("");

    for(i = 0; i < F_StrLen(*mainString); i++)
    {
   
      strBuf = F_StrCopyString(*mainString);
   
      //Truncate the string from the beginning
      F_StrReverse(strBuf, 10000);
      F_StrTrunc(strBuf, (F_StrLen(strBuf) - i));
      F_StrReverse(strBuf, 10000);

      //and lop it down to the size of the search string
      if(F_StrLen(strBuf) > F_StrLen(searchString))

        //jimmy the loop so we step past the length of the replacement
        //string the next time around
        i += F_StrLen(searchString) - 1;
