Alloc(nuint)

Allocates a block of memory of the specified size, in bytes (分配指定大小的内存块（以字节为单位）).

[CLSCompliant(false)]
public static void* Alloc(nuint byteCount)

Parameters

byteCount nuint

The size, in bytes, of the block to allocate (要分配的块的大小（以字节为单位）).

Returns

void*

A pointer to the allocated block of memory (指向分配的内存块的指针).

Remarks

This method allows byteCount to be 0 and will return a valid pointer that should not be dereferenced and that should be passed to free to avoid memory leaks (此方法允许 byteCount 为 0 ，将返回一个有效的指针, 该指针不应被取消引用, 应传递给 free 以避免内存泄漏).

This method is a thin wrapper over the C malloc API (此方法是 C malloc API 上的精简包装器).

Exceptions

OutOfMemoryException

Allocating byteCount of memory failed.

Alloc(nuint, nuint)

Allocates a block of memory of the specified size, in elements (按元素分配指定大小的内存块).

[CLSCompliant(false)]
public static void* Alloc(nuint elementCount, nuint elementSize)

Parameters

elementCount nuint

The count, in elements, of the block to allocate (要分配的块的数量（以元素为单位）).

elementSize nuint

The size, in bytes, of each element in the allocation (分配中每个元素的大小（以字节为单位）).

Returns

void*

A pointer to the allocated block of memory (指向分配的内存块的指针).

Remarks

This method allows elementCount and/or elementSize to be 0 and will return a valid pointer that should not be dereferenced and that should be passed to free to avoid memory leaks (此方法允许 elementCount/ elementSize 为 0 ，将返回一个有效的指针, 该指针不应被取消引用, 应传递给 free 以避免内存泄漏).

This method is a thin wrapper over the C malloc API (此方法是 C malloc API 上的精简包装器).

Exceptions

OutOfMemoryException

Allocating elementCount * elementSize bytes of memory failed.
