_get_amblksiz

Gets the current block size used in memory allocations.

errno_t _get_amblksiz( 
   size_t * blockSize 
);

Parameters

  • [out] blockSize
    The block size will be written to this variable.

Return Value

Zero if successful; an error code on failure.

Remarks

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.
