	System cppsupport initialization.

详细描述

宏定义说明

AFTER_SCATTER

#define AFTER_SCATTER   1

If LOS_CppSystemInit() is called in the second stage of scatter load, this flag should be passed as the third parameter.

BEFORE_SCATTER

#define BEFORE_SCATTER   0

If LOS_CppSystemInit() is called in the first stage of scatter load, this flag should be passed as the third parameter.

NO_SCATTER

#define NO_SCATTER   2

If scatter load is disabled, this flag should be passed as the third parameter when LOS_CppSystemInit() is called.

函数说明

LOS_CppSystemInit()

INT32 LOS_CppSystemInit ( UINTPTR  initArrayStart, UINTPTR  initArrayEnd, INT32  flag  )

extern

System cppsupport initialization.

Description:

This API is used to initialize the cppsupport.

注意

• initArrayStart is the start address of .init_array section, initArrayEnd is the end address of .init_array section.
• initArrayStart must be smaller than initArrayEnd, initArrayStart and initArrayEnd should be 4(32 bits platform) or 8(64 bits platform) bytes alignment.

参数

initArrayStart	[IN] Start address of init_array section.
initArrayEnd	[IN] End address of init_array section.
flag	[IN] The flag indicating when LOS_CppSystemInit() is called, BEFORE_SCATTER, AFTER_SCATTER or NO_SCATTER.

返回值

LOS_OK	Initialization succeeded.
LOS_NOK	The entered parameter is incorrect, initialization failed.

Dependency:

• los_cppsupport.h: the header file that contains the API declaration.
