_get_sbh_threshold

Returns the upper limit for the size of a memory allocation that will be supported by the small-block heap.

size_t _get_sbh_threshold( void );

Return Value

Returns the upper limit for the size of a memory allocation that will be supported by the small-block heap.

Remarks

_get_sbh_threshold gets the current threshold value for the small-block heap. The default threshold size is 1016 bytes for Windows 95, 98, ME and Windows NT, and zero for Windows 2000 and later platforms. By default, the small-block heap is not used on Windows 2000 and later platforms, though _set_sbh_threshold can be called with a nonzero value to enable the small-block heap in those instances.

Requirements

Routine Required header Compatibility
_get_sbh_threshold <malloc.h> Win 98, Win Me, Win NT, Win 2000, Win XP
