NAME
acl_get_perm — test for a permission in an ACL permission setLIBRARY
Linux Access Control Lists library (libacl, -lacl).SYNOPSIS
#include <sys/types.h> #include <acl/libacl.h> int acl_get_perm(acl_permset_t permset_d, acl_perm_t perm);DESCRIPTION
The acl_get_perm() function tests if the permission specified by the argument perm is con‐ tained in the ACL permission set pointed to by the argument permset_d. Any existing descriptors that refer to permset_d continue to refer to that permission set.RETURN VALUE
If successful, the acl_get_perm() function returns 1 if the permission specified by perm is contained in the ACL permission set permset_d, and 0 if the permission is not contained in the permission set. 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_perm() function returns -1 and sets errno to the corresponding value: [EINVAL] The argument permset_d is not a valid descriptor for a permission set within an ACL entry. The argument perm is not a valid acl_perm_t value.STANDARDS
This is a non-portable, Linux specific extension to the ACL manipulation functions defined in IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned).SEE ALSO
