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 indi- cated 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 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)
