Function xmlRealloc 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn xmlRealloc(
    ptr: *mut c_void,
    size: usize,
) -> *mut c_void

Reallocate memory.

UPSTREAM-PARITY

void *xmlRealloc(void *ptr, size_t size);

Changes the size of the memory block pointed to by ptr. If ptr is NULL, behaves like xmlMalloc. If size is 0, may return NULL (like C realloc).

SAFETY

• ptr must be a valid pointer from xmlMalloc, xmlMallocAtomic, or xmlRealloc, or NULL
• The returned pointer must be freed with xmlFree
