DI_PROM_PROP_LOOKUP_BYTES(3DEVINFO)	   DI_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(3DEV‐
		    INFO).

       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.
