I guess the code to use that from C would look something like this:
SCM
scm_c_eval_string_from_file (const char *string,
const char *file_name,
long line, long column)
{
static SCM eval_string_var, file_keyword, line_keyword, column_keyword;
static int initialized = 0;
SCM args[7];
if (!initialized)
{
eval_string_var = scm_c_public_variable ("ice-9 eval-string",
"eval-string");
file_keyword = scm_from_latin1_keyword ("file");
line_keyword = scm_from_latin1_keyword ("line");
column_keyword = scm_from_latin1_keyword ("column");
initialized = 1;
}
args[0] = scm_from_locale_string (string);
args[1] = file_keyword;
args[2] = scm_from_locale_string (file_name);
args[3] = line_keyword;
args[4] = scm_from_long (line);
args[5] = column_keyword;
args[6] = scm_from_long (column);
return scm_call_n (SCM_VARIABLE_REF (eval_string_var), args, 7);
}
This seems very awkward. Is there an easier way?
