    Command:

    acl_get_perm

    
    
    
    

    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 contained 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).
