SYNOPSIS         top

       const char * context_str(context_t con);

       void context_free(context_t con);

       const char * context_role_get(context_t con);

       const char * context_user_get(context_t con);

       int context_type_set(context_t con, const char *type);

       int context_range_set(context_t con, const char *range);

       int context_user_set(context_t con, const char *user);

DESCRIPTION         top

       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() 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

       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.

RETURN VALUE         top

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

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

       On failure errno is set appropriately.
