acl_add_perm - add permissions to a permission set

 

NAME

      acl_add_perm - add permissions to a permission set
 

LIBRARY

      Standard C Library (libc, -lc)
 

SYNOPSIS

      #include <sys/types.h>
      #include <sys/acl.h>
 
      int
      acl_add_perm(acl_permset_t permset_d, acl_perm_t perm);
 

DESCRIPTION

      The acl_add_perm() function is a POSIX.1e call that adds the permission
      contained in perm to the permission set permset_d.
 
      Note: it is not considered an error to attempt to add permissions that
      already exist in the permission set.
      The acl_add_perm() 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

      The acl_add_perm() function fails if:
 
      [EINVAL]           Argument permset_d is not a valid descriptor for a
                         permission set within an ACL entry.  Argument perm
                         does not contain a valid acl_perm_t value.
      acl(3), acl_clear_perms(3), acl_delete_perm(3), acl_get_permset(3),
      acl_set_permset(3), posix1e(3)
 

STANDARDS

      POSIX.1e is described in IEEE POSIX.1e draft 17.
