Function emalloc 

pub fn emalloc(layout: Layout) -> *mut u8

Uses the PHP memory allocator to allocate request-bound memory.

The Zend allocator only guarantees ZEND_MM_ALIGNMENT (8 bytes) and has no aligned-allocation entry point, so a layout requesting a stricter alignment cannot be honoured and yields a null pointer.

Parameters

• layout - The layout of the requested memory.

Returns

A pointer to the memory allocated, or null if layout.align() exceeds ZEND_MM_ALIGNMENT.
