call method - AllocatorAlloc extension - dart:ffi library (original) (raw)

call<T extends SizedNativeType> method

Pointer<T> call<T extends SizedNativeType>([

1. int count = 1 ])

Allocates sizeOf<T>() * count bytes of memory using allocate.

// This allocates eight bytes, which is enough space for two Int32's.
allocator<Int32>(2);

This extension method must be invoked with a compile-time constant T.

To allocate a specific number of bytes, not just a multiple ofsizeOf<T>(), use allocate. To allocate with a non constant T, use allocate. Prefer call for normal use, and use allocate for implementing anAllocator in terms of other allocators.

Implementation

external Pointer<T> call<T extends SizedNativeType>([int count = 1]);
