I want to call scheme from C.

The C loop scans the binary data and a scheme script would be used to accept/reject a record. Something like


         ./my-c-program --filter '(and (is-male?) (is-german?) )' persons.data > male_from_germany.data

right, if I call scheme fro C should I put my library in a directory or is there any way to embed the code in the C executable (in a const char*...)

hum not sure .. again, here my program is a C code, and I want to provide a guile program that would be used as a filter for each record.


./my-c-program --filter '(and (is-male?) (is-german?) )' persons.data > male_from_germany.data


I hope it's clearer now
