But how can I get these values of C preprocessor definitions in my Pascal program?

Please note, that "asmname" is deprecated.

In C

int foo = FOO_CONST;

where FOO_CONST is defined somewhere else.

In Pascal:

var MyFoo: Integer; attribute (name='foo') ; external; (untested)

Better yet:

const int foo = FOO_CONST;

var MyFoo: Integer; attribute (name = 'foo', const, external); ^^^^^

Then the compiler treats the variable as constant, so it can't be modified in the Pascal code by accident.

Alternative:

Pascal:

const foo = 42; { whichever value you choose }

C:

#define foo 42 /* same value as in Pascal */

void LogMessage (int Priority, char* MessagePtr) { [...] syslog (Priority == foo : FOO_CONST ? Priority == bar : BAR_CONST ? ... , MessagePtr); }

Hope you get the idea.

Then you have a constant in Pascal (but not necessarily the same value as FOO_CONST in C).
