standard c library for escaping a string

Question

Is there a standard C library function to escape C-strings?

For example, if I had the C string:

char example[] = "first line
second line: "inner quotes"";

And I wanted to print

"first line
second line: "inner quotes""

Is there a library function that will do that transformation for me? Rolling my own just seems a little silly.

Bonus points if I can give it a length to escape (so it stops before or beyond the ).

If you were writing GPL stuff you might use http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/quotearg.c;hb=HEAD
