.Nd get a value from the hints mechanism
.Sh SYNOPSIS
.In sys/param.h
.In sys/bus.h
.Ft int
.Fn resource_int_value "const char *name" "int unit" "const char *resname" "int *result"
.Ft int
.Fn resource_long_value "const char *name" "int unit" "const char *resname" "long *result"
.Ft int
.Fn resource_string_value "const char *name" "int unit" "const char *resname" "const char **result"
.Sh DESCRIPTION
These functions fetch a value from the
.Dq hints
mechanism.
.Pp
The functions take the following arguments:
.Bl -tag -width "resname"
.It Fa name
The name of the device to get the resource value from.
.It Fa unit
The unit number of the device.
\-1 is special and is used for wildcard entries.
.It Fa resname
The resource name.
.It Fa result
A pointer to memory in which to store the resource value.
.El
.Sh RETURN VALUES
If successful, the functions return 0.
Otherwise, a non\-zero error code is returned.
.Sh ERRORS
The functions will fail if:
.Bl -tag -width Er
.It Bq Er ENOENT
The resource could not be found.
.It Bq Er EFTYPE
Inappropriate resource type.
.El
.Sh SEE ALSO
.Xr device 9 ,
.Xr driver 9
