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.
Name
context_new, context_str, context_free, context_type_get, context_type_set, context_range_get,
context_range_set,context_role_get, context_role_set, context_user_get, context_user_set - Routines to
manipulate SELinux security contexts
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.
