m_label_dup(3tsol)

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 <tsol/label.h>

       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 allo‐
       cated resources by calling m_label_free().


       The m_label_free() function frees resources that  are  associated  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. Oth‐
       erwise, -1 is returned and errno is set to indicate the error.

ERRORS
       The m_label_alloc() function will fail if:

       EINVAL    Invalid parameter.


       ENOMEM    The physical limits of the system are exceeded by size  bytes
                 of memory which cannot be allocated.
