#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.

Execution Environment

The sol_close entry point can be called from the process environment only.

Return Values

ENODEV Indicates that the specified minor number is not valid.

Implementation Specifics

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.
