declared by:
$ALIAS EXTIN = 'EXTIN"' (%REF, %REF, %VAL, %VAL, %VAL, %VAL, %REF, %REF)
or the intrinsic statement could be used:
SYSTEM INTRINSIC HPEXTIN
In HP C/XL, the intrinsic pragma is used to declare an intrinsic. For
example, instead of using the following declaration:
extern void HPPACCVDA( );
you could write:
#pragma intrinsic HPPACCVDA
The function names ending with a prime (EXTIN', for example) can be
called by HP Pascal or HP FORTRAN 77/XL programs using the ALIAS command.
See the HP Pascal Reference Manual or the HP FORTRAN 77/XL Reference
Manual for a detailed description of the ALIAS command. For example,
specify the following statement in your HP Pascal program:
PROCEDURE EXTIN $ALIAS 'EXTIN"'$;INTRINSIC;
Or specify the following statement in your HP FORTRAN 77/XL program:
$ALIAS EXTIN = 'EXTIN"' (%REF, %REF, %VAL, %VAL, %VAL, %VAL, %REF, %REF)
