acl_set_qualifier

Linux Access Control Lists library (libacl, -lacl).

n sys/types.h n sys/acl.h

The function sets the qualifier of the ACL entry indicated by the argument to the value referred to by the argument If the value of the tag type in the ACL entry referred to by is ACL_USER, then the value referred to by shall be of type If the value of the tag type in the ACL entry referred to by is ACL_GROUP, then the value referred to by shall be of type If the value of the tag type in the ACL entry referred to by is a tag type for which a qualifier is not supported, returns an error.

Any ACL entry descriptors that refer to the entry referred to by continue to refer to that entry. This function may cause memory to be allocated. The caller should free any releasable memory, when the ACL is no longer required, by calling with a pointer to the ACL as argument.

If any of the following conditions occur, the function returns and sets to the corresponding value:

• EINVAL The argument is not a valid descriptor for an ACL entry.

The value of the tag type in the ACL entry referenced by the argument is neither ACL_USER nor ACL_GROUP.

The value pointed to by the argument is not valid.

ENOMEM The function is unable to allocate the memory required for the ACL qualifier.
