SYNOPSIS

#include <mknod.h>

HP-UX COMPATIBILITY

Level: HP-UX/STANDARD

Origin: HP

DESCRIPTION

Mknod.h provides utilities to pack and unpack device names as used by mknod(2). It contains the macro dev = makedev(major, minor) which packs the major and minor fields into a form suitable for mknod(2). It also contains major(dev) and minor(dev) which extract the corresponding fields. 

The macro MINOR_FORMAT is a printf specification that prints the minor field in the format best suited to the particular implementation.  The specification given by MINOR_FORMAT must cause the resulting string to indicate the base of the number in the same format as that used for C: no leading zero for decimal, leading zero for octal, and leading zero and ’x’ for hexadecimal. 

When a minor field is printed in the format specified by MINOR_FORMAT, each sub-field contained in the minor will be wholly contained in the mininum possible number of digits of the resulting string.  (Splitting a field across unnecessary digits for the sake of packing is not done.)

WARNING

All of the macros defined in <mknod.h> are also defined in <sys/sysmacros.h> for Bell System V compatibility.  Mknod.h only exists for compatibility with previous releases of HP-UX, and should not be used for new development.
