NAME
       RegisterTextBufferScanFunctions

SYNOPSIS
      #include <textbuff.h>
        ...
      extern void RegisterTextBufferScanFunctions(forward, backward)
      char * (*forward)();
      char * (*backward)();

DESCRIPTION
      The RegisterTextBufferScanFunctions procedure provides the capability to
      replace the scan functions used by the ForwardScanTextBuffer and
      BackwardScanTextBuffer functions.  These functions are called as:

            (*forward)(string, curp, expression);
            (*backward)(string, curp, expression);

      and are responsible for returning either a pointer to the begining of a
      match for the expression or NULL.

      Calling this procedure with NULL function pointers reinstates the default
      regular expression facility.
