p They take the following arguments: l -tag -width "resname" t Fa name name of the device to get the resource value from. t Fa unit unit number of the device. -1 is special and is used for wildcard entries. t Fa resname resource name. t Fa result pointer to a memory in which to store the resource value. .El .Sh RETURN VALUES If successful, functions return 0. Otherwise, a non-zero error code is returned. .Sh ERRORS Functions will fail if: l -tag -width Er t Bq Er ENOENT The resource could not be found. t Bq Er EFTYPE Inappropriate resource type. .El .Sh SEE ALSO .Xr device 9 , .Xr driver 9 .Sh AUTHORS This manual page was written by .An Warner Losh Aq imp@FreeBSD.org .
