MALLOCX_LG_ALIGN

public static int MALLOCX_LG_ALIGN(int la)

Align the memory allocation to start at an address that is a multiple of (1 << la). This macro does not validate that la is within the valid range.

Parameters:

la - the alignment shift

MALLOCX_ALIGN

public static int MALLOCX_ALIGN(int a)

Align the memory allocation to start at an address that is a multiple of a, where a is a power of two. This macro does not validate that a is a power of 2.

Parameters:

a - the alignment

MALLOCX_TCACHE

public static int MALLOCX_TCACHE(int tc)

Use the thread-specific cache (tcache) specified by the identifier tc, which must have been acquired via the tcache.create mallctl. This macro does not validate that tc specifies a valid identifier.

Parameters:

tc - the thread-specific cache

MALLOCX_ARENA

public static int MALLOCX_ARENA(int a)

Use the arena specified by the index a (and by necessity bypass the thread cache). This macro has no effect for huge regions, nor for regions that were allocated via an arena other than the one specified. This macro does not validate that a specifies an arena index in the valid range.

Parameters:

a - the arena index
