   7 .SH NAME
   8 ddi_intr_get_nintrs, ddi_intr_get_navail \- return number of interrupts
   9 supported or available for a given interrupt type
  10 .SH SYNOPSIS

  25 
  26 .SH INTERFACE LEVEL

  97 the given \fItype\fR supported by a particular hardware device. On a successful
  98 return, the number of supported interrupts is returned as an integer pointed to
  99 by the \fInintrsp\fR argument.
 100 .sp
 101 .LP
 102 If the hardware device is not found to support any interrupts of the given
 103 \fItype\fR, the \fBDDI_INTR_NOTFOUND\fR failure is returned rather than a zero
 104 in \fInintrsp\fR.
 105 .sp
 106 .LP
 107 The \fBddi_intr_get_navail()\fR function returns the number of interrupts of a
 108 given \fItype\fR that is available to a particular hardware device. On a
 109 successful return, the number of available interrupts is returned as an integer
 110 pointed to by \fInavailp\fR.
 111 .sp
 112 .LP
 113 The hardware device may support more than one interrupt and can request that
 114 all interrupts be allocated. The host software can then use policy-based
 115 decisions to determine how many interrupts are made available to the device.
 116 Based on the determination, a value is returned that should be used to allocate
 117 interrupts with the \fBddi_int_alloc()\fR function.
 118 .sp
 119 .LP
 120 The \fBddi_intr_get_supported_types\fR(9F) function returns a list of valid
 121 supported types for the given hardware device. It must be called prior to
 122 calling either the \fBddi_intr_get_nintrs()\fR or \fBddi_intr_get_navail()\fR.
 123 .SH RETURN VALUES

 127 return:
