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(3DEV- INFO) 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).
