NAME

       di_prom_prop_data, di_prom_prop_next, di_prom_prop_name - access PROM device information

SYNOPSIS

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

       di_prom_prop_t di_prom_prop_next(di_prom_handle_t ph, di_node_t node, di_prom_prop_t prom_prop);

       char *di_prom_prop_name(di_prom_prop_t prom_prop);

       int di_prom_prop_data(di_prom_prop_t prom_prop, uchar_t **prop_data);

PARAMETERS

       node	       Handle to a device node in the snapshot of kernel device tree.

       ph	       PROM handle

       prom_prop       Handle to a PROM property.

       prop_data       Address of a pointer.

DESCRIPTION

       The  di_prom_prop_next()  function  obtains  a  handle to the next property on the PROM property list associated with node. If prom_prop is
       DI_PROM_PROP_NIL, the first property associated with node is returned.

       The di_prom_prop_name() function returns the name of the prom_prop property.

       The di_prom_prop_data() function returns the value of the prom_prop property. The return value is a  non-negative  integer  specifying  the
       size in number of bytes in prop_data.

       All memory allocated by these functions is managed by the library and must not be freed by the caller.

RETURN VALUES

       The  di_prom_prop_data() function returns the number of bytes in prop_data and prop_data is updated to point to a byte array containing the
       property value. If  0 is returned, the property is a boolean property and the existence of this property indicates the value is true.

       The di_prom_prop_name() function returns a pointer to a string that contains the name of prom_prop.

       The di_prom_prop_next() function returns a handle to the next PROM property. DI_PROM_PROP_NIL  is  returned  if	no  additional	properties
       exist.

ERRORS

       See openprom(7D) for a description of possible errors.
