invent_geometry(9r)
NAME
  invent_geometry - Disk: Calculates device geometry information

SYNOPSIS
  int invent_geometry(
	  struct DEVGEOMST *geom );

ARGUMENTS
  geom
      Specifies a pointer to the disk's geometry structure.

DESCRIPTION
  The invent_geometry interface calculates a device geometry when supplied
  with a  disk capacity (geom->geom_info.dev_size).   The interface supplies
  the number of sectors, the number of tracks, and the number of cylinders
  that describes a geometry  for the given disk capacity.

  The disk driver's DEVGETGEOM ioctl command calls the invent_geometry
  interface when no geometry information is available.

RETURN VALUES
  Upon successful completion, invent_geometry returns the value zero (0).
  Otherwise, it returns the value 1 to indicate a geometry could not be
  invented.
