- * GetOpenMode --
- *
- * Description:
- * Computes a POSIX mode mask from a given string and also sets
- * a flag to indicate whether the caller should seek to EOF during
- * opening of the file.
- *
- * Results:
- * On success, returns mode to pass to "open". If an error occurs, the
- * returns -1 and if interp is not NULL, sets the interp's result to an
- * error message.
- *
- * Side effects:
- * Sets the integer referenced by seekFlagPtr to 1 if the caller
- * should seek to EOF during opening the file.
- *
- * Special note:
- * This code is based on a prototype implementation contributed
- * by Mark Diekhans.
