Description
Each buffer type and sub-type must have an entry in the tm_typesw array such that when a buffer is manipulated the appropriate routines are called. For the buffer types provided by the BEA Tuxedo system, see tuxtypes(5).
An application wishing to supply their own buffer type can do so by adding an instance to the tm_typesw array in $TUXDIR/lib/tmtypesw.c (tuxtypes(5) shows how this can be done). The semantics of the routines which must be supplied when adding a new type are specified in buffer(3).
