NAME

ioctlprint — display descriptive ioctl value

SYNOPSIS

DESCRIPTION

The ioctlprint utility displays information about the file ioctl operation pointed to by one or more arg arguments. The argument can either be an ioctl(2) symbolic name or the ioctl value.

The options are as follows:

-e emulation

If an emulation of a process is unknown, interpret system call maps assuming the named emulation instead of default "netbsd".

-f format

The argument is a printf(3) style format string that allows customization of ioctlprint's output.

The following conversion characters can be used:

%E

Symbolic decoded ioctl string.

%e

Decoded ioctl string with hex values.

%n

Descriptive ioctl operation name.

%x

Hexadecimal ioctl number.

%o

Octal ioctl number.

%d or %i

Decimal ioctl number.

The default format is:

"%n %e %x\n"

-l

List all known ioctl(2) requests.

The ioctlprint command first appeared in NetBSD 10.
