Revision 1.2 2000/01/05 08:20:39 markster
|
|
Some OSS fixes and a few lpc changes to make it actually work
|
|
|
|
* Revision 1.2 1996/08/20 20:40:51 jaf
|
|
* Removed all static local variables that were SAVE'd in the Fortran
|
|
* code, and put them in struct lpc10_encoder_state that is passed as an
|
|
* argument.
|
|
*
|
|
* Removed init function, since all initialization is now done in
|
|
* init_lpc10_encoder_state().
