VARSTRING Structures
Following are the structures used in messages from the SNAX/CM server interface. If
the structure contains variable-length information, it should use the VARSTRING
structure to be an offset and length to it. A VARSTRING structure is defined as
follows:
STRUCT VARSTRING (*);
BEGIN
INT OFFSET; ! Byte offset to data. It is the offset
! from the outermost structure that the
! varstring is contained in (usually the
! base of the message).
INT LENGTH; ! Byte length of data, 0 = not present.
END; -- struct varstring
STRUCT proc^buffer^template (*);
BEGIN
STRING base[ 0:-1];
INT(32) proc^queue^ptr;
INT lu^index;
INT type;
INT file1[ 0:11 ];
INT file2[ 0:11 ];
STRUCT parmstring( VARSTRING );
STRING data[ 0:-1 ];
END;
STRUCT connected^buffer^template (*);
BEGIN
STRING base[ 0:-1];
INT(32) connected^queue^ptr;
INT type;
INT linename[ 0:3 ];
INT portname[ 0:17 ]
STRUCT parm( VARSTRING );
STRING data[ 0:-1 ];
END;
User Procedure LITERALS
Following are the user procedure literals for the server:
LITERAL
true = -1, ! boolean for ON
false = 0, ! boolean for OFF
fecontinue = 70; ! continue file operation
