ACL_GET_PERMSET(3)					   BSD Library Functions Manual 					ACL_GET_PERMSET(3)

NAME

     acl_get_permset -- retrieve the permission set from an ACL entry

LIBRARY

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

SYNOPSIS

     #include <sys/types.h>
     #include <sys/acl.h>

     int
     acl_get_permset(acl_entry_t entry_d, acl_permset_t *permset_p);

DESCRIPTION

     The acl_get_permset() function returns in permset_p a descriptor to the permission set in the ACL entry indicated by entry_d.  Subsequent
     operations using the returned permission set descriptor operate on the permission set within the ACL entry.

     Any ACL entry descriptors that refer to the entry referred to by entry_d shall continue to refer to those entries.

RETURN VALUE

     The acl_get_permset() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to
     indicate the error.

ERRORS

     If any of the following conditions occur, the acl_get_permset() function returns -1 and sets errno to the corresponding value:

     [EINVAL]		The argument entry_d is not a valid descriptor for an ACL entry.

STANDARDS

     IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)

ACL_SET_QUALIFIER(3)					   BSD Library Functions Manual 				      ACL_SET_QUALIFIER(3)

NAME

     acl_set_qualifier -- set the qualifier of an ACL entry

LIBRARY

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

SYNOPSIS

     #include <sys/types.h>
     #include <sys/acl.h>

     int
     acl_set_qualifier(acl_entry_t entry_d, const void *qualifier_p);

DESCRIPTION

     The acl_set_qualifier() function sets the qualifier of the ACL entry indicated by the argument entry_d to the value referred to by the argu-
     ment qualifier_p.	If the value of the tag type in the ACL entry referred to by entry_d is ACL_USER, then the value referred to by
     qualifier_p shall be of type uid_t.  If the value of the tag type in the ACL entry referred to by entry_d is ACL_GROUP, then the value
     referred to by qualifier_p shall be of type gid_t.  If the value of the tag type in the ACL entry referred to by entry_d is a tag type for
     which a qualifier is not supported, acl_set_qualifier() returns an error.

     Any ACL entry descriptors that refer to the entry referred to by entry_d 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 acl_free() with a pointer to the
     ACL as argument.

RETURN VALUE

     The acl_set_qualifier() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set
     to indicate the error.

ERRORS

     If any of the following conditions occur, the acl_set_qualifier() function returns -1 and sets errno to the corresponding value:

     [EINVAL]		The argument entry_d is not a valid descriptor for an ACL entry.

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

			The value pointed to by the argument qualifier_p is not valid.

     [ENOMEM]		The acl_set_qualifier() function is unable to allocate the memory required for the ACL qualifier.

STANDARDS

     IEEE Std 1003.1e draft 17 ("POSIX.1e", abandoned)
