.Dd September 26, 2015 .Dt BUS_GET_RESOURCE 9 .Os .Sh NAME .Nm bus_get_resource .Nd "read a resource range/value with a given resource ID" .Sh SYNOPSIS n sys/param.h n sys/bus.h n sys/rman.h .Ft int .Fo bus_get_resource .Fa "device_t dev" "int type" "int rid" "rman_res_t *startp" "rman_res_t *countp" .Fc .Sh DESCRIPTION The .Fn bus_get_resource function reads the range or value of the resource .Fa type , rid pair and stores it in the .Fa startp and .Fa countp arguments.

p The arguments are as follows: l -tag -width ".Fa startp" t Fa dev The device to read the resource from. t Fa type The type of resource you want to read. It is one of:

p l -tag -width ".Dv SYS_RES_MEMORY" -compact t Dv SYS_RES_IRQ for IRQs t Dv SYS_RES_DRQ for ISA DMA lines t Dv SYS_RES_MEMORY for I/O memory t Dv SYS_RES_IOPORT for I/O ports .El t Fa rid A bus-specific handle that identifies the resource being read. t Fa startp A pointer to the start address of this resource. t Fa countp A pointer to the length of the resource. For example, the size of the memory in bytes. .El .Sh RETURN VALUES Zero is returned on success, otherwise an error is returned. .Sh SEE ALSO .Xr bus_set_resource 9 , .Xr device 9 , .Xr driver 9 .Sh AUTHORS This manual page was written by .An Sascha Wildner .
