Trusted Extensions Library Functions               m_label(3TSOL)



NAME
     m_label, m_label_alloc, m_label_dup, m_label_free -  m_label
     functions

SYNOPSIS
     cc [flag...] file... -ltsol [library...]


     #include 

     m_label_t *m_label_alloc(const m_label_type_t label_type);


     int m_label_dup(m_label_t **dst, const m_label_t *src);


     void m_label_free(m_label_t *label);


DESCRIPTION
     The m_label_alloc() function allocates resources for  a  new
     label.  The label_type argument defines the type for a newly
     allocated label. The label type can be:

     MAC_LABEL     A Mandatory Access Control (MAC) label.


     USER_CLEAR    A user clearance.



     The m_label_dup() function allocates resources for a new dst
     label.  The  function  returns  a  pointer  to the allocated
     label, which is an exact copy of the src label.  The  caller
     is  responsible  for freeing the allocated resources by cal-
     ling m_label_free().


     The m_label_free() function frees resources that are associ-
     ated with the previously allocated label.

RETURN VALUES
     Upon successful  completion,  the  m_label_alloc()  function
     returns  a  pointer to the newly allocated label. Otherwise,
     m_label_alloc() returns NULL and errno is  set  to  indicate
     the error.


     Upon  successful  completion,  the  m_label_dup()   function
     returns  0.  Otherwise,  -1  is returned and errno is set to
     indicate the error.
