ACL_DELETE_PERM(3) Library Functions Manual ACL_DELETE_PERM(3)
acl_delete_perm — delete a permission from an ACL permission set
Linux Access Control Lists library (libacl, -lacl).
<sys/types.h> <sys/acl.h> int acl_delete_perm(acl_permset_t
permset_d, acl_perm_t perm)
The acl_delete_perm() function deletes the permission contained
in the argument perm (one of ACL_READ, ACL_WRITE, ACL_EXECUTE)
from the permission set referred to by the argument permset_d.
An attempt to delete a permission that is not contained in the
permission set is not considered an error.
Any existing descriptors that refer to permset_d continue to
refer to that permission set.
The acl_delete_perm() function returns the value 0 if successful;
otherwise the value -1 is returned and the global variable errno
is set to indicate the error.
If any of the following conditions occur, the acl_delete_perm()
function returns -1 and sets errno to the corresponding value:
[EINVAL] The argument permset_d is not a valid
descriptor for a permission set within an ACL
entry.
The argument perm does not contain a valid
acl_perm_t value.
