di_prom_init(3DEVINFO)				       Device Information Library Functions				    di_prom_init(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(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). ATTRIBUTES

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. ATTRIBUTES
