sys_exit

Applicability

Function Usage

Deinitializes the low-level hardware of the media data processing system after media data, such as images and videos, is processed.

Prototype

• C Prototype

  1	hi_s32 hi_mpi_sys_exit()

• Python Function

  1	ret = acl.himpi.sys_exit()

Parameter Description

None.

Return Value Description

Restrictions

• Repeated calls to this API return no failures.
• After this API is called for deinitialization, the resources for processing media data in the system are freed. Therefore, APIs (except acl.himpi.sys_init) in the media data processing V2 section cannot be called. Otherwise, exceptions may occur during API calling or the return code may be incorrect.
• This API must be called before runtime resources are freed. For details about the runtime resource allocation process, see Runtime Resource Allocation.
