int sol_close ( devno, chan)
dev_t devno;
int chan;
| devno | Specifies major and minor device numbers. |
| chan | Specifies the channel number assigned by the sol_mpx entry point. |
The sol_close entry point is called when a user-mode caller issues a close subroutine. The sol_close entry point can also be invoked in response to an fp_close kernel service.
The sol_close entry point functions with a Serial Link Adapter and Serial Optical Channel Converter, that have been correctly configured for use on a qualified network. Consult the hardware specifications for more information on configuring hardware and network qualifications.
The sol_close entry point can be called from the process environment only.
| ENODEV | Indicates that the specified minor number is not valid. |
