How to programmatically access NFS share using Windows API

  • Article

Recently, we got a case where the customer wanted to programmatically access NFS share using Windows API.

We have an API “WNetAddConnection2” which can be used programmatically for accessing NFS share. So we tested and wrote a code for the customer using this API to mount the NFS share.

The usage of the code is: (where username and Password are optional)

TestWNetAddConnection2.exe <Local Drive Name> <Remote Name> <User Name - optional> <Password - optional>

Example:

TestWNetAddConnection2.exe X: xxx.xx.xxx.xx:/nfsshare

Code: You would need to build the code according to your environment.
