NAME
     diproplookupbytes,                   diproplookupints,
     diproplookupint64,  diproplookupstrings - search for a
     property

SYNOPSIS
     cc [ flag... ] file... -ldevinfo [ library... ]
     #include 

     int diproplookupbytes(devt dev, dinodet node,
          const char *propname, uchart **propdata);


     int diproplookupints(devt dev, dinodet node,
          const char *propname, int **propdata);


     int diproplookupint64(devt dev, dinodet node,
          const char *propname, int64t **propdata);


     int diproplookupstrings(devt dev, dinodet node,
          const char *propname, char **propdata);


PARAMETERS
     dev          devt of minor node with which the property  is
                  associated.  DIDEVTANY  is a wild card that
                  matches all devt's, including DIDEVTNONE.


     node         Handle to the device node with which  the  pro-
                  perty is associated.


     propdata    For diproplookupbytes(), the  address  to  a
                  pointer to an array of unsigned characters con-
                  taining the property data.

                  For diproplookupints(),  the  address  to  a
                  pointer  to an array of integers containing the
                  property data.

                  For diproplookupint64(), the  address  to  a
                  pointer to an array of 64-bit integers contain-
                  ing the property data.

                  For diproplookupstrings(), the address to  a
                  pointer  to a buffer containing a concatenation
                  of null-terminated strings containing the  pro-
                  perty data.

     propname    Name of the property for which to search.


DESCRIPTION
     These functions return the value of a  known  property  name
     type  and  devt  value. All memory allocated by these func-
     tions is managed by the library and must not be freed by the
     caller.

RETURN VALUES
     If the property is found, the number of entries in propdata
     is  returned.  If  the  property  is  a  boolean  type, 0 is
     returned and the existence of this  property  indicates  the
     value is true. Otherwise, -1 is returned and errno is set to
     indicate the error.

ERORS
     These functions will fail if:

     EINVAL     Invalid argument.


     ENOTSUP    The snapshot contains no property information.


     ENXIO      The    property    does    not     exist;     try
                dipromproplookup*().

     butes:
