498 
499    Input Parameters:
500 +  name_scheme - name of user-defined acceptance scheme
501 .  path - path (either absolute or relative) the library containing this scheme
502 .  name_create - name of routine to create method context
503 -  routine_create - routine to create method context
504 
505    Notes:
506    TSGLAcceptRegisterDynamic() may be called multiple times to add several user-defined families.
507 
508    If dynamic libraries are used, then the fourth input argument (routine_create)
509    is ignored.
510 
511    Sample usage:
512 .vb
513    TSGLAcceptRegisterDynamic("my_scheme",/home/username/my_lib/lib/libO/solaris/mylib.a,
514                              "MySchemeCreate",MySchemeCreate);
515 .ve
516 
517    Then, your scheme can be chosen with the procedural interface via
518 $     TSGLSetAcceptType(ts,"my_scheme")
519    or at runtime via the option
520 $     -ts_gl_accept_type my_scheme
