.SH "ARGUMENTS"
.PP
\fIdev\fR

.SH "DESCRIPTION"
.PP
This function tries to allocate a maximum possible number of interrupts in a range between
\fIminvec\fR
and
\fImaxvec\fR\&. It returns a negative errno if an error occurs\&. If it succeeds, it returns the actual number of interrupts allocated and updates the
\fIdev\fR\*(Aqs irq member to the lowest new interrupt number; the other interrupt numbers allocated to this device are consecutive\&.
