FAUTH(2) FAUTH(2) NAME fauth - set up authentication on a file descriptor to a file server SYNOPSIS #include <u.h> #include <libc.h> int fauth(int fd, char *aname) DESCRIPTION Fauth is used to establish authentication for the current user to access the resources available through the 9P con- nection represented by fd. The return value is a file descriptor, conventionally called afd, that is subsequently used to negotiate the authentication protocol for the server, typically using auth_proxy or fauth_proxy (see auth(2)). After successful authentication, afd may be passed as the second argument to a subsequent mount call (see bind(2)), with the same aname, as a ticket-of-entry for the user. If fauth returns -1, the error case, that means the file server does not require authentication for the connection, and afd should be set to -1 in the call to mount. It is rare to use fauth directly; more commonly amount (see auth(2)) is used.
