Arguments

 

position

   OpenVMS usage:longword_signed
   type:         longword integer (signed)
   access:       read only
   mechanism:    by reference

   Starting position, relative to the base address, of the bit field
   to be searched by LIB$FFx. The position argument is the address
   of a signed longword integer containing the starting position.
 

size

   OpenVMS usage:byte_unsigned
   type:         byte (unsigned)
   access:       read only
   mechanism:    by reference

   Number of bits to be searched by LIB$FFx. The size argument is
   the address of an unsigned byte containing the size of the bit
   field to be searched. The maximum size is 32 bits.
 

base

   OpenVMS usage:address
   type:         longword (unsigned)
   access:       read only
   mechanism:    by reference

   The base argument is the address of the bit field that LIB$FFx
   searches.
 

find-position

   OpenVMS usage:longword_signed
   type:         longword integer (signed)
   access:       write only
   mechanism:    by reference

   Bit position of the first bit in the specified state (clear or
   set), relative to the base address. The find-position argument
   is the address of a signed longword integer into which LIB$FFC
   writes the position of the first clear bit and into which LIB$FFS
   writes the position of the first set bit.
