Provides the attributes of the tokfastwrt entry point.
The CIO_GET_FASTWRT tokioctl operation is used to get the parameters required to issue the tokfastwrt entry point, which is the kernel-mode fast write command for the token-ring device handler. For the CIO_GET_FASTWRT operation, the arg parameter points to the cio_get_fastwrt structure. This structure is defined in the /usr/include/sys/comio.h file and contains the following fields:
status | Returns one of the following status values: |
fastwrt_fn | Specifies the address of the tokfastwrt entry point. |
chan | Specifies the channel ID. |
devno | Specifies the major and minor device numbers. |
The CIO_GET_FASTWRT tokioctl operation can be called from the kernel-mode process environment only.
The CIO_GET_FASTWRT tokioctl operation functions with a Token-Ring High Performance Network Adapter that has been correctly configured for use on a qualified network. Consult the adapter specifications for more information on configuring the adapter and network qualifications.
