功能概述

hbmem api使用说明，包括com buffer、graphic buffer、graphic buffer group、queue、pool、share pool的创建使用，多进程共享等。

软件架构说明

本文基于libhbmem API实现，调用libhbmem提供的API，实现不同buffer类型的内存申请和进程间共享。

编译环境

本文的编译环境使用SDK中的build工具，请参考: :doc:`Build环境建立 `。

编译说明

本文主要依赖libhbmem提供的头文件：

#include

编译依赖的库有如下：

LIBS += -lhbmem -lpthread -lalog -ldl -lstdc++

编译命令

# 进入SDK所有目录{sdk_dir}，并source构建环境（参见上）。

# 编译本sample:

bdm libhbmem-sample

# 输出文件:

{sdk_dir}/out/debug-gcc_{gcc_version}/build/test/samples/platform_samples/source/S83_Sample/S83E02_Communication/libhbmem_sample
