|
|
* Revision history:
|
|
* 10/25/02 brr Clean up function prototypes & include files.
|
|
* 04/03/02 spm Removed use of daemon. Changed existing interfaces to
|
|
* return N8_FILE_ERROR. Removed init interface.
|
|
* 03/18/02 bac Added debugging information for daemon failures.
|
|
* 03/13/02 brr Make n8_daemon_init reentrant to support BSD initialization.
|
|
* 03/08/02 msz No more system semaphores.
|
|
* 02/22/02 spm Changed keyEntryName_p type class to const in sks_write.
|
|
* 02/22/02 spm Converted printk's to DBG's.
|
|
* 02/05/02 spm Removed const typing. Reverted to using N8_Status_t,
|
|
* as opposed to the original daemon status.
|
|
* 01/28/02 spm Removed finish semaphore and replaced it with n8_usleep.
|
|
* This will cause the SKS daemon interfaces to sleep for
|
|
* a specified timeout, rather than potentially blocking the
|
|
* caller forever.
|
|
* 01/22/02 spm Added include of n8_sks.h. NOTE: we will want
|
|
* to move this header to common/include_private.
|
|
* 01/20/02 spm Serialized access to daemon. Split interface
|
|
* into internal and functional halves.
|
|
* 01/17/02 spm Fixed some debug statements.
|
|
* 01/16/02 spm Revamp for integration w/ /wing/SDK-2.1
|
|
* 12/17/01 spm Original version.
