IOCTLPRINT(1) FreeBSD General Commands Manual IOCTLPRINT(1)
NAME
ioctlprint - display descriptive ioctl value
SYNOPSIS
ioctlprint [-l] [-e emulation] [-f format] [arg ...]
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.
