       These functions allow an application to	manipulate  the	 fields	 of  a
       security	 context string without requiring it to know the format of the

       context_new() returns a new context initialized to a context string.

       context_str() returns a pointer to the string value of  the  context_t,
       valid  until  the  next call to context_str() or context_free() for the
       same context_t*.

       context_free() frees the storage used by a context.

       context_type_get(),	context_range_get(),	   context_role_get(),
       context_user_get()  get a pointer to the string value of a context com‐

       Note: Values returned by the get functions are  only  valid  until  the
       next  call  to  a set function or context_free() for the same context_t

       context_type_set(),	context_range_set(),	   context_role_set(),
       context_user_set() set a context component.

       On failure context_*_set() functions return non-zero and 0 on success.

       The other functions return NULL on failure and non-NULL on success.

       On failure errno is set appropriately.
