Prev	Chapter 35. Extending CLISP	Next

If you must be able to access the Lisp variable in the C code, follow these steps:

declare the variable name in constsym.d in the appropriate package (probably “CUSTOM”, if there is no specific package);
add a define_variable() call in function init_symbol_values() in file spvw.d;
export your variable name from the appropriate package in file init.lisp;
