Description:

The fs_crypto_domain_lock_dynamic() function locks a dynamic domain, preventing access to the original contents of any file belonging to the given domain until later unlocked.

Note:
  • In order to use filesystem encryption, download the Encrypted Filesystem package from the QNX Software Center.
  • You must be in the group that owns the filesystem's mountpoint in order to lock a domain.

This function sets the variable pointed to by preply to one of the following values:

FS_CRYPTO_REPLY_ALREADY
The domain was already locked.
FS_CRYPTO_REPLY_COMPLETE
The domain is now locked.
FS_CRYPTO_REPLY_INVALID
The command wasn't completed successfully.
FS_CRYPTO_REPLY_NOENTRY
No entry was found for the given domain.
FS_CRYPTO_REPLY_UNKNOWN_TYPE
The type of encryption used for the domain is invalid.

Returns:

EOK
Success.
EINVAL
Invalid arguments.
ENOMEM
Insufficent free memory.

This function can also return any of the errors indicated by devctl() or open().
