NAME

       i2o_cntxt_list_add - Append a pointer to context list and return a id

SYNOPSIS

       u32 i2o_cntxt_list_add(struct i2o_controller * c, void * ptr);

ARGUMENTS

       c
	   controller to which the context list belong

       ptr
	   pointer to add to the context list

DESCRIPTION

       Because the context field in I2O is only 32-bit large, on 64-bit the pointer is to large to fit in the context field. The i2o_cntxt_list
       functions therefore map pointers to context fields.

       Returns context id > 0 on success or 0 on failure.

NAME

       ibv_open_device, ibv_close_device - open and close an RDMA device context

SYNOPSIS

       #include <infiniband/verbs.h>

       struct ibv_context *ibv_open_device(struct ibv_device *device);

       int ibv_close_device(struct ibv_context *context);

DESCRIPTION

       ibv_open_device() opens the device device and creates a context for further use.

       ibv_close_device() closes the device context context.

RETURN VALUE

       ibv_open_device() returns a pointer to the allocated device context, or NULL if the request fails.

       ibv_close_device() returns 0 on success, -1 on failure.

NOTES

       ibv_close_device()  does  not  release all the resources allocated using context context.  To avoid resource leaks, the user should release
       all associated resources before closing a context.
