di_path_prop_lookup_bytes, di_path_prop_lookup_int64s, di_path_prop_lookup_ints, di_path_prop_lookup_strings - search for a path property
cc [ flag... ] file... -ldevinfo [ library... ] #include <libdevinfo.h> int di_path_prop_lookup_bytes(di_path_t path, const char *prop_name); int di_path_prop_lookup_int64s(di_path_t path, const char *prop_name); int di_path_prop_lookup_ints(di_path_t path, const char *prop_name, char **prop_data); int di_path_prop_lookup_strings(di_path_t path, const char *prop_name, char **prop_data);
path The handle to a path node in a di_init(3DEVINFO). prop_name The name of property for which to search. prop_data For di_path_prop_lookup_bytes(), the address to a pointer to an array of unsigned characters containing the property data. For di_path_prop_lookup_int64(), the address to a pointer to an array of 64-bit integers containing the property data. For di_path_prop_lookup_ints(), the address to a pointer to an array of integers containing the property data. For di_path_prop_lookup_strings(), the address to a pointer to a buffer containing a concatenation of null-terminated strings containing the property data.
These functions return the value of a known property name and type. All memory allocated by these functions is managed by the library and must not be freed by the caller.
If the property is found, the number of entries in prop_data is returned. Otherwise, -1 is returned and errno is set to indicate the error.
These functions will fail if: EINVAL One of the arguments is invalid. ENOTSUP The snapshot contains no property information. ENXIO The path property does not exist.
