* @brief This file implements the driver half of the N8 daemon ioctl
* mechanism.
*
*----------------------------------------------------------------------------
* Key Handle File Functional Interfaces
* (See sdk/common/include_private/n8_daemon_sks.h)
*----------------------------------------------------------------------------
*
* n8_daemon_sks_read - Reads data from the specified key handle file into
* a key handle structure.
*
* n8_daemon_sks_write - Write data in key handle specified into a key
* handle file with specified name.
*
* n8_daemon_sks_delete - Deletes specified key handle file from the host
* file system.
*
* n8_dameon_sks_reset - Deletes all key handle files from host
* file system.

*****************************************************************************/
/*****************************************************************************
* 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.
