Resets the Serial Optical Link (SOL) device handler to a known state and frees system resources.
#include <sys/device.h> #include <sys/comio.h> #include <sys/soluser.h>
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 can be called from the process environment only.
|ENODEV||Indicates that the specified minor number is not valid.|
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.
