acl_set_qualifier(3)
NAME
  acl_set_qualifier - Sets the tag qualifier (UID or GID) on an ACL entry

SYNOPSIS
  #include <sys/acl.h>

  int acl_set_qualifier(
	  acl_entry_t entry_d,
	  void *tag_qualifier_p );

LIBRARY
  Security Library (libpacl.a)

PARAMETERS
  entry_d
      Designates the working storage internal representation ACL entry to set
      the tag qualifier in.

  tag_qualifier_p
      Designates the uid or gid to set the tag qualifier to.

DESCRIPTION
  NOTE:	 This function is based on Draft 13 of the POSIX P1003.6 standard.

  Given an ACL entry, the acl_set_qualifier() function sets the id in the ACL
  entry. If the tag type of the given ACL entry is ACL_USER then
  tag_qualifier_p is evaluated as a pointer of type *uid_t. If the tag type
  of the given ACL entry is ACL_GROUP then tag_qualifier_p is evaluated as a
  pointer of type *gid_t. Any other ACL tag type results in an error.

RETURN VALUES
  Upon successful completion, the acl_set_qualifier() function returns a
  value of 0 (zero).  Otherwise, a value of -1 is returned and errno is set
  to indicate the error.

ERRORS
  If any of the following conditions occur, the acl_set_qualifier() function
  sets errno to the corresponding value:

  [EINVAL]
      Argument entry_d does not refer to a valid ACL entry.  The value of the
      tag type in ACL entry referred to by entry_d is ACL_USER_OBJ,
      ACL_GROUP_OBJ, or ACL_OTHER_OBJ. The value of the entry in
      tag_qualifier_p is not valid.

  [ENOMEM]
      There is not enough memory available  to allocate the ACL uid/gid
      storage.
