NAME

       getdmapent, getdmapnam, getdmaptype, getdmaptdev, setdmapent, enddmapent, setdmapfile - get device_maps entry

SYNOPSIS

       cc  [flag...] file... -lbsm  [library...]

       #include <bsm/devices.h>

       devmap_t *getdmapent(void);

       devmap_t *getdmapnam(char *name);

       devmap_t *getdmapdev(char *name);

       devmap_t *getdmaptype(char *type);

       void setdmapent(void);

       void enddmapent(void);

       void setdmapfile(char *file);

DESCRIPTION

       The  getdmapent(), getdmapnam(), getdmapdev(), and getdmaptype() functions each return a device_deallocate entry. The getdmapent() function
       enumerates all device_maps entries. The getdmaptype() function enumerates device_maps entries with a given device type. Successive calls to
       these  functions  return  either  successive device_maps entries or NULL. The getdmapnam() function searches for a device_maps entry with a
       given device allocation name. The getdmapdev() function searches for a device_maps entry containing a given device special file.

       The internal representation of a device_maps entry is a devmap_t structure defined in <bsm/devices.h> with the following members:

       char *dmap_devname;     /* device allocation name */
       char *dmap_devtype;     /* generic device type */
       char *dmap_devlist;     /* list of associated device special files */

       The setdmapent() function "rewinds" to the beginning of the enumeration of device_maps entries. Calls to getdmapnam() may leave the enumer-
       ation in an indeterminate state, so setdmapent() should be called before the first call to getdmapent() or getdmaptype().

       The  enddmapent()  function  can  be  called  to  indicate  that  device_maps  processing  is complete. The library can then close any open
       device_maps file, deallocate any internal storage, and so forth.

       The setdmapfile() function changes the pathname used by the other functions for opening the device_maps file, allowing use  of  device_maps
       files other than the default file, /etc/security/device_maps.

RETURN VALUES

       The  getdmapent() and getdmaptype() functions return a pointer to a devmap_t if they successfully enumerate an entry. Otherwise they return
       NULL, indicating the end of the enumeration.

       The getdmapnam() function returns a pointer to a devmap_t if it successfully locates the requested entry. Otherwise it returns NULL.

FILES

       /etc/security/device_maps

	   Administrative file defining the mapping of device special files to allocatable device names.

NOTES

       The getdmapent(), getdmapnam(), getdmapdev(), and getdmaptype() functions allocate memory for the pointers they return. This memory can	be
       deallocated with the free(3C) function.
