di_prom_fini(3DEVINFO)

Name

di_prom_init, di_prom_fini - create and destroy a handle to the PROM device information

Synopsis

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

di_prom_handle_t di_prom_init(void);
void di_prom_fini(di_prom_handle_t  ph);

Parameters

ph

Handle to prom returned by di_prom_init().

Description

For device nodes whose nodeid value is DI_PROM_NODEID (see di_nodeid(3DEVINFO)), additional properties can be retrieved from the PROM. The di_prom_init() function returns a handle that is used to retrieve such properties. This handle is passed to di_prom_prop_lookup_bytes(3DEVINFO) and di_prom_prop_next(3DEVINFO).

The di_prom_fini() function destroys the handle and all handles to the PROM device information obtained from that handle.

Return Values

Upon successful completion, di_prom_init() returns a handle. Otherwise, DI_PROM_HANDLE_NIL is returned and errno is set to indicate the error.

Errors

The di_prom_init() sets errno function to any error code that can also be set by openprom(7D) or malloc(3C).
