IOCTLPRINT(1)           NetBSD 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 opera-
     tion 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.
