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 en‐
tries.

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 corre‐
sponding 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)
