 Just use rb_eval_string_protect()

pigeon% cat tt.c
#include <ruby.h>
 
static VALUE
tt(obj, str)
    VALUE obj, str;
{
    VALUE result;
    int state = 0;
 
    result = rb_eval_string_protect(RSTRING(str)->ptr, &state);
    if (state) {
        result = rb_inspect(rb_gv_get("$!"));
    }
    return result;
}
 
void Init_tt()
{
    rb_define_global_function("cex", tt, 1);
}

pigeon% ruby -rtt -e 'cex "def a"'
pigeon%
