c - converting an array of characters to a const gchar*

I've got an array of characters which contains a string:

char buf[MAXBUFLEN];
buf[0] = 'f';
buf[1] = 'o';
buf[2] = 'o';
buf[3] = '';

I'm looking to pass this string as an argument to the gtk_text_buffer_insert function in order to insert it into a GtkTextBuffer. What I can't figure out is how to convert it to a const gchar *, which is what gtk_text_buffer_insert expects as its third argument.

Can anybody help me out?

gchar is just a typedef for char and the conversion from arrays to const pointers is implicit, so you can just pass it:

someFunctionExpectingConstGcharPointer(buf);

Note that you can also directly initialize arrays with string literals:

char buf[MAXBUFLEN] = "foo";
