wait / sleep until a remote file is unlocked in c

On a sftp server i create a "lockfile.lock" if another application is manipulating data. No in my c application i would like to check if the lockfile.lock exists and than "WAIT 5 SECONDS".

How do i wait 5 seconds in c without blasting the CPU to 100%?

Thanks
