di_prom_prop_lookup_bDeviceDInformation Libdi_prom_prop_lookup_bytes(3DEVINFO)

NAME
       di_prom_prop_lookup_bytes,		     di_prom_prop_lookup_ints,
       di_prom_prop_lookup_strings - search for a PROM property

SYNOPSIS
       cc [ flag... ] file... -ldevinfo [ library... ]
       #include <libdevinfo.h>

       int  di_prom_prop_lookup_bytes(di_prom_handle_t	ph,  di_node_t	 node,
       const char *prop_name, uchar_t **prop_data);

       int di_prom_prop_lookup_ints(di_prom_handle_t ph, di_node_t node, const
       char *prop_name, int **prop_data);

       int di_prom_prop_lookup_strings(di_prom_handle_t	 ph,  di_node_t	 node,
       const char *prop_name, char **prop_data);

PARAMETERS
       node	       Handle	to   device   node   in	 snapshot  created  by
		       di_init(3DEVINFO).

       ph	       Handle returned by di_prom_init(3DEVINFO).

       prop_data       For  di_prom_prop_lookup_bytes(),  the  address	of   a
		       pointer to an array of unsigned characters.

		       For   di_prom_prop_lookup_ints(),   the	address	 of  a
		       pointer to an integer.

		       For  di_prom_prop_lookup_strings(),  the	  address   of
		       pointer to a buffer.

       prop_name       The name of the property being searched.

DESCRIPTION
       These  functions	 return	 the  value  of a known PROM property name and
       value type and update the prop_data pointer to  reference  memory  that
       contains the property value. All memory allocated by these functions 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	 prop_data  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.

       For di_prom_prop_lookup_bytes(), the number of entries is the number of
       unsigned characters contained in the buffer pointed to by prop_data.

       For di_prom_prop_lookup_ints(), the number of entries is the number  of
       integers contained in the buffer pointed to by prop_data.

       For  di_prom_prop_lookup_strings(), the number of entries is the number
       of null-terminated strings contained in the  buffer.  The  strings  are
       stored in a concatenated format in the buffer.

ERRORS
       These functions will fail if::

       EINVAL	       Invalid argument.

       ENXIO	       The property does not exist.
