acl_get_permset

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)
