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  exis-
       tence 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.
