Arguments

 

type

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value
   Type of storage to be written over with the erase pattern. The
   type argument is a longword containing the type of storage.

   The three storage types, together with their symbolic names,
   are defined by the $ERADEF macro and are listed in the following
   table:

   Storage Type   Symbolic Name

   Main memory    ERA$K_MEMORY
   Disk           ERA$K_DISK
   Tape           ERA$K_TAPE
 

count

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value
   Number of times that $ERAPAT has been called in a single security
   erase operation. The count argument is a longword containing the
   iteration count.

   You should call the $ERAPAT service initially with the count
   argument set to 1, the second time with the count argument set to
   2, and so on, until the status code SS$_NOTRAN is returned.
 

patadr

   OpenVMS usage:longword_unsigned
   type:         longword (unsigned)
   access:       write only
   mechanism:    by reference
   Security erase pattern to be written. The patadr argument is the
   address of a longword into which the security erase pattern is to
   be written.
