Could not find the ``mpn_invert" function

[Md Al-Amin KHANDAKER]

​Dear all,

I was trying to to implement modular integer inversion using mpn functions.
Before I used mpz_invert. But there is no nearly similar name fucntion for
mpn. I searched and found the following discussion.
https://gmplib.org/list-archives/gmp-devel/2009-December/001355.html
​Is the mpn_invert fuction inlcuded in gmp 6.1.2?

Thank you,
Amin
