注意

None.

参数

None.

返回值

None.

Dependency:

los_scatter.h: the header file that contains the API declaration.

参见: None.

Description:: This API is used to define the type of a flash-reading function, so that it can be called to read data from a certain flash.

注意

None.

参数

memAddr	[IN] The memory starting address where to write the data reading from a certain flash.
start	[IN] The starting address to read data from a certain flash.
size	[IN] The size of data reading from a certain flash.

返回值

INT32 The size of data read from flash.

Dependency:

los_scatter.h: the header file that contains the API declaration.

参见: None.
