Arguments

 

enbflg

   OpenVMS usage:boolean
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value
   Indicator specifying whether the specified privileges are to be
   enabled or disabled. The enbflg argument is a longword value.
   The value 1 indicates that the privileges specified in the prvadr
   argument are to be enabled. The value 0 (the default) indicates
   that the privileges are to be disabled.
 

prvadr

   OpenVMS usage:mask_privileges
   type:         quadword (unsigned)
   access:       read only
   mechanism:    by reference
   Privileges to be enabled or disabled for the calling process. The
   prvadr argument is the address of a quadword bit vector wherein
   each bit corresponds to a privilege that is to be enabled or
   disabled.

   Each bit has a symbolic name. The $PRVDEF macro defines these
   names. You form the bit vector by specifying the symbolic
   name of each desired privilege in a logical OR operation. The
   following table provides the symbolic name and description of
   each privilege:

   If you do not specify prvadr or assign it the value 0, the
   privileges are not altered.
 

prmflg

   OpenVMS usage:boolean
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value
   Indicator specifying whether the privileges are to be affected
   permanently or temporarily. The prmflg argument is a longword
   value. The value 1 specifies that the privileges are to be
   affected permanently, that is, until you change them again
   by using $SETPRV or until the process is deleted. The value 0
   (the default) specifies that the privileges are to be affected
   temporarily, that is, until the current image exits (at which
   time the permanently enabled privileges of the process will be
   restored).

   Setting the prmflg argument to nonzero changes privilege bits in
   both the CURPRIV mask and the PROCPRIV mask.
 

prvprv

   OpenVMS usage:mask_privileges
   type:         quadword (unsigned)
   access:       write only
   mechanism:    by reference
   Privileges previously possessed by the calling process. The
   prvprv argument is the address of a quadword bit vector wherein
   each bit corresponds to a privilege that was previously either
   enabled or disabled. If you do not specify prvprv or assign it
   the value 0, the previous privilege mask is not returned.
