DESCRIPTION

39       These functions allow an application to  manipulate  the  fields  of  a
40       security  context string without requiring it to know the format of the
41       string.
42
43       context_new
44        Return a new context initialized to a context string
45
46       context_str Return a pointer to the string value of the context_t Valid
47       until  the  next  call to context_str or context_free for the same con‐
48       text_t*
49
50       context_free Free the storage used by a context
51
52       context_type_get, context_range_get, context_role_get, context_user_get
53       Get a pointer to the string value of a context component
54
55       NOTE:  Values  returned  by  the get functions are only valid until the
56       next call to a set function or context_free() for  the  same  context_t
57       structure.
58
59       context_type_set, context_range_set, context_role_set, context_user_set
60       Set a context component
61
62

RETURN VALUE

64       On success, zero is returned. On failure, -1 is returned and  errno  is
65       set appropriately.
