create an ACL from text
Linux Access Control Lists library (libacl, -lacl).
() function converts the text form
of the ACL referred to by buf_p
internal form of an ACL and returns a pointer to the working storage that
contains the ACL. The acl_from_text
accepts as input the long text form and short text form of an ACL as described
This function may cause memory to be allocated. The caller should free any
releasable memory, when the new ACL is no longer required, by calling
() as an argument.
On success, this function returns a pointer to the working storage. On error, a
is returned, and
is set appropriately.
If any of the following conditions occur, the
() function returns a value of
to the corresponding value:
- The argument buf_p cannot
be translated into an ACL.
- The acl_t to be returned
requires more memory than is allowed by the hardware or system-imposed
memory management constraints.
