oaMemory

模块: oapy._oa._base 导入: from oapy._oa import _base

概览

oaMemory 在 oapy 中可用，可通过 _base 模块访问。

本页汇总 oaMemory 当前在 oapy 中可用的 Python 接口。

详细说明

The oaMemory class is a utility class that encapsulates and adds error checking to the memory management functions, including: malloc , realloc , and free 。 Using these allocation routines instead of new or delete is more efficient on some platforms。

方法说明

_base.oaMemory.get(size)

绑定状态: 已绑定

Python 调用: _base.oaMemory.get(size)

This function gets a block of memory of the specified size in bytes and returns a pointer to it。 The allocation is made by making a call to malloc( ) 。

异常

• oacMemGetFailed。

Python 示例

from oapy._oa import _base

_base.oaMemory.get(size)

_base.oaMemory.resize(ptr, size)

绑定状态: 已绑定

Python 调用: _base.oaMemory.resize(ptr, size)

This function resizes a block of memory specified by ptr to the specified size in bytes and returns a pointer to the new block of memory。 The memory is resized by making a call to realloc( ) 。 The contents of the existing memory are unchanged。 Specifying size as zero frees the memory。

异常

• oacMemResizeFailed。

Python 示例

from oapy._oa import _base

_base.oaMemory.resize(ptr, size)

_base.oaMemory.free(ptr)

绑定状态: 已绑定

Python 调用: _base.oaMemory.free(ptr)

This function makes memory previously allocated by the get() or resize() functions available for further allocation。

Python 示例

from oapy._oa import _base

_base.oaMemory.free(ptr)
