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

context_new
 Return a new context initialized to a context string 

context_str
 Return 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
 Free 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 component

.B 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 structure.

context_type_set, context_range_set, context_role_set, context_user_set
 Set a context component

.SH "RETURN VALUE"
On success, zero is returned. On failure, -1 is returned and errno is
set appropriately.
