Writing C Modules with Inline::C

The C code is placed after the __DATA__ symbol. Below __DATA__, __C__ marks 

the start of the C code:

__DATA__

__C__

#include 

char * file_type (char *filename) {

  return gnome_mime_type(filename);

}

I'll discuss the actual C code in the next section.

A First Inlined Function

Just as in the first XS example in the last chapter, I'll start with the gnome_mime_type()

function. This function takes a filename as an argument and returns a string con 

taining the MIME type of the filename. It has the following signature:

const char * gnome_mime_type(const gchar *filename);

One way to wrap this function is shown in Listing 10 2, with the function 

file_type():

char * file_type (char *filename) {

  return gnome_mime_type(filename);

}

With this function in place, test.pl can be written:

use Test::More  no_plan ;

BEGIN { use_ok( Gnome::MIME ); }

# test some simple mime file_type recognitions

is(Gnome::MIME::file_type("foo.gif"),   image/gif ,  "recognizes .gif");

is(Gnome::MIME::file_type("foo.jpg"),   image/jpeg , "recognizes .jpg");

is(Gnome::MIME::file_type("foo.html"),  text/html ,  "recognizes .html");
