:relfileprefix: ../../../
:mrdocs:

Allocate sufficient capacity to store at least the specified `numBuffers` buffers. The behavior is undefined unless `0 <= numBuffers`. Note that this method does not change the length of this blob or add any buffers to it. Note also that the internal capacity will be increased to maintain a geometric growth factor.
