SYNOPSIS DESCRIPTION RETURN VALUES ERRORS SEE ALSO AUTHORS

#include <sys/param.h>

#include <sys/bus.h>

int
resource_int_value(const char *name, int unit, const char *resname, int *result);

int
resource_long_value(const char *name, int unit, const char *resname, long *result);

int
resource_string_value(const char *name, int unit, const char *resname, const char **result);

These functions fetch a value from the "hints" mechanism.

The functions take the following arguments:

name
	The name of the device to get the resource value from.
unit
	The unit number of the device. -1 is special and is used for wildcard entries.
resname
	The resource name.
result
	A pointer to memory in which to store the resource value.

If successful, the functions return 0. Otherwise, a non-zero error code is returned.

The functions will fail if:

[ENOENT]
	The resource could not be found.
[EFTYPE]
	Inappropriate resource type.
