acl.himpi.sys_close_epoll

C Prototype	hi_s32 hi_mpi_sys_close_epoll(hi_s32 epoll_fd)
Python Function	ret = acl.himpi.sys_close_epoll(epoll_fd)
Function Usage	Closes the epoll instance of media data processing when the epoll model is used to perform input and output operations on the media data processing channel. The Atlas 200/300/500 Inference Product does not support this API. The Atlas Training Series Product does not support this API.
Input Description	epoll_fd: int, pointer address of the processing epoll instance handle of the media data to be destroyed. The handle is created by calling acl.himpi.sys_create_epoll.
Return Value	ret: int, error code. 0 indicates success. Other values: failure. For details, see Common Return Codes.
Restrictions	acl.himpi.sys_create_epoll, acl.himpi.sys_ctl_epoll, acl.himpi.sys_wait_epoll, and acl.himpi.sys_close_epoll must be used together to operate the input and output data of the media data processing channel by using the epoll programming model. The VPC function does not support this API.
