.SH NAME
modinfo \- display information about loaded kernel modules
.SH SYNOPSIS
.LP
.nf
\fB/usr/sbin/modinfo\fR [\fB-c\fR] [\fB-w\fR] [\fB-i\fR \fImodule-id\fR]
.fi

.SH DESCRIPTION
.sp
.LP
The \fBmodinfo\fR utility displays information about the loaded modules. The
format of the information is as follows:
.sp
.in +2
.nf
\fIId\fR \fILoadaddr\fR \fISize\fR \fIInfo\fR \fIRev\fR \fIModule Name\fR
.fi
.in -2

.sp
.LP
where \fIId\fR is the module ID, \fILoadaddr\fR is the starting text address in
hexadecimal, \fISize\fR is the size of text, data, and bss in hexadecimal
bytes, \fIInfo\fR is module specific information, \fIRev\fR is the revision of
the loadable modules system, and \fIModule Name\fR is the filename and
description of the module.
.sp
.LP
The module specific information is the block and character major numbers for
drivers, the system call number for system calls, and unspecified for other
module types.
