Function Documentation

◆ G_whoami()

const char* G_whoami ( void  )

Gets user's name.

Returns a pointer to a string containing the user's login name.

Tries getlogin() first, then goes to the password file. However, some masscomp getlogin() fails in ucb universe because the ttyname(0) rotuine fails in ucb universe. So we check for this, too.

Returns
pointer to string ("anonymous" by default)
