Hello,
I want to understand how Zend MM works, so i'm looking trought the sources and i see this: #define ZEND_MM_ALIGNMENT_MASK ~(ZEND_MM_ALIGNMENT-1) #define ZEND_MM_ALIGNED_SIZE(size) (((size) + ZEND_MM_ALIGNMENT - 1) & ZEND_MM_ALIGNMENT_MASK) I understand that the first define will create something like 11111000 ( it will clear last 3 bits) but what does the 2nd define? Before clearing the last 3 bytes why does it add ZEND_MM_ALIGNMENT- 1 to size? Thanks,
