# SNB

A string name block (SNB) is a pointer to an array of pointers to strings, that ends in a NULL pointer. String name blocks are used by the IStorage interface and by function calls that open storage objects. The strings point to contained storage objects or streams that are to be excluded in the open calls.

Remarks

The SNB should be created by allocating a contiguous block of memory in which the pointers to strings are followed by a NULL pointer, which is then followed by the actual strings.

The marshaling of a string name block is based on the assumption that the SNB passed in was created this way. Although it could be stored in other ways, the SNB created in this manner has the advantage of requiring only one allocation operation and one freeing of memory for all the strings.
