.SH NAME
proc_info \- supports /proc/scsi/{driver_name}/{host_no}
.SH SYNOPSIS
.sp
\fB
.sp
int proc_info  (char * \fIbuffer\fB, char ** \fIstart\fB, off_t \fIoffset\fB, int \fIlength\fB, int \fIhostno\fB, int \fIwriteto1_read0\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIbuffer\fB\fR
anchor point to output to (0==writeto1_read0) or fetch from
(1==writeto1_read0).
.TP
\fB\fIstart\fB\fR
where ``interesting'' data is written to. Ignored when
1==writeto1_read0.
.TP
\fB\fIoffset\fB\fR
offset within buffer 0==writeto1_read0 is actually
interested in. Ignored when 1==writeto1_read0 .
.TP
\fB\fIlength\fB\fR
maximum (or actual) extent of buffer
.TP
\fB\fIhostno\fB\fR
-- undescribed --
.TP
\fB\fIwriteto1_read0\fB\fR
1 -> data coming from user space towards driver
(e.g. ``echo some_string > /proc/scsi/xyz/2'')
0 -> user what data from this driver
(e.g. ``cat /proc/scsi/xyz/2'')
.SH "DESCRIPTION"
.PP
Returns length when 1==writeto1_read0. Otherwise number of chars
output to buffer past offset.
.SH "LOCKS"
.PP
none held
.SH "CALLING CONTEXT"
.PP
process
.SH "NOTES"
.PP
Driven from scsi_proc.c which interfaces to proc_fs. proc_fs
support can now be configured out of the scsi subsystem.
