vme_ivec_alloc(D3X)vme_ivec_alloc(D3X)NAMEvme_ivec_alloc - allocate a VME bus interrupt VECTOR
SYNOPSIS
#include <sys/types.h>
#include <sys/ddi.h>
int vme_ivec_alloc(uint_t adapter);
Arguments
adapter
The adapter number identifying which VME bus on the system.
DESCRIPTION
For Challenge and Onyx systems, vme_ivec_alloc dynamically allocates an
interrupt vector for the specified VME bus. With vme_ivec_set(D3X), a
driver can allocate and register more than one VME interrupt vector for a
single board. vme_ivec_alloc(D3X) and vme_ivec_set(D3X) are used in
edtinit() routines.
Return Values
vme_ivec_alloc returns -1 if no vectors remain or the adapter specified
is invalid.
