SYNOPSIS

string expand_define (string name)
string expand_define (string name, string arg, ...)

DESCRIPTION

Expands the macro <name> with the argument(s) <arg>... (default is one empty string ""). Result is the expanded macro, or 0 if there is no macro with that name.

This efun is applicable only while an object is compiled, therefore its usage is restricted to a few functions like the H_INCLUDE_DIRS driver hook, or the masters runtime_error() function.

EXAMPLE

	While compiling 'foo.c'
	  expand_define("__FILE__") --> "file.c"

HISTORY

Introduced in 3.2.1@93.
