NAME
di_prop_lookup_bytes, di_prop_lookup_ints, di_prop_lookup_int64, di_prop_lookup_strings - search for a property SYNOPSIS
cc [ flag... ] file... -ldevinfo [ library... ] #include <libdevinfo.h> int di_prop_lookup_bytes(dev_t dev, di_node_t node, const char *prop_name, uchar_t **prop_data); int di_prop_lookup_ints(dev_t dev, di_node_t node, const char *prop_name, int **prop_data); int di_prop_lookup_int64(dev_t dev, di_node_t node, const char *prop_name, int64_t **prop_data); int di_prop_lookup_strings(dev_t dev, di_node_t node, const char *prop_name, char **prop_data); PARAMETERS
dev dev_t of minor node with which the property is associated. DDI_DEV_T_ANY is a wild card that matches all dev_t's, including DDI_DEV_T_NONE. node Handle to the device node with which the property is associated. prop_data For di_prop_lookup_bytes(), the address to a pointer to an array of unsigned characters containing the property data. For di_prop_lookup_ints(), the address to a pointer to an array of integers containing the property data. For di_prop_lookup_int64(), the address to a pointer to an array of 64-bit integers containing the property data. For di_prop_lookup_strings(), the address to a pointer to a buffer containing a concatenation of null-terminated strings containing the property data. prop_name Name of the property for which to search. DESCRIPTION
These functions return the value of a known property name type and dev_t 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. ERRORS
These functions will fail if: EINVAL Invalid argument. ENOTSUP The snapshot contains no property information. ENXIO The property does not exist; try di_prom_prop_lookup_*(). ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ |MT-Level |Safe | +-----------------------------+-----------------------------+ SEE ALSO
