Заметки
The _amblksiz global variable controls the block size used by the memory allocation functions such as malloc. This function provides a secure way of getting access to the value of this variable.
If blockSize is NULL, this function invokes an invalid parameter handler, as described in Parameter Validation. If execution is allowed to continue, this function returns -1 and sets errno to EINVAL.
