/*
 -  StringReplace
 -
 *  Purpose:
 *      Replace occurances of one character by another in an input string.
 *      This function is destructive of the input string.
 *
 *  Arguments:
 *      [in][out] sz - Manipulated string.
 *      [in] src - Character to be replaced.
 *      [in] dst - Character to replace to.
 *
 *  Returns:
 *      LPSTR Address of resulted string. 
 *
 *  Remarks:
 *      Used primarily to replace occurances of \n by \0 in the string resource
 *      for the file filters of the Print To File dialog box.
