Function            strtabexpand - expand tabs to spaces

  Syntax              char *strtabexpand(char *source, char *dest,
                                         int tablen);

  Prototype in        stringhk.h

  Remarks             copies the string source to dest with all tabs
                      ('\t') replaced with tablen spaces.

                      The converted string will be returned in dest, so
                      you must make sure there is sufficient space
                      allocated.

  Return value        returns dest.

                           char spacestr[30];
                           char tabstr[30] = "Tabs\tare\tnice.";

                           printf("Converted string: %s\n",
                                  strtabexpand(tabstr,spacestr,4);
                      }
