Arguments

 

efn

   OpenVMS usage:integer
   type:         longword bit mask (unsigned)
   access:       read
   mechanism:    by value
   Number of the event flag to be set when the IO_FASTPATH(W)
   operation completes. The efn argument is a longword containing
   the number of the event flag.
 

cpu_mask

   OpenVMS usage:bitmap
   type:         quadword bitmap
   access:       read
   mechanism:    by 32- or 64-bit reference
   The cpu_mask argument specifies a set of CPUs to be operated
   upon.
 

function_code

   OpenVMS usage:integer
   type:         longword (unsigned)
   access:       read
   mechanism:    by value
   The function_code specifies the operation to be performed. Note
   that there is currently only one function code:

   FP$K_BALANCE_PORTS - Distribute Fast Path ports across CPUs.
 

mask_length

   OpenVMS usage:integer
   type:         longword length
   access:       read
   mechanism:    by value
   The mask_length specifies the length of the cpu_mask bitmap in
   bytes. If the mask_length is not supplied or is specified as
   zero, a length of 4 bytes is used.
