Do you include a prototype for read_data() in main.c? This would
probably be done by creating 'scanner.h', and putting a prototype
struct provided_data *read_data(char *input_file_name);
in there. If there's no prototype, then the C compiler will, for
historical reasons, assume that the function is actually
int read_data(...);
and so you're then trying to assign the result of read_data
(implicitly an int) to input_data (a pointer).
