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() 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 component.

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.

Return Value

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.
