If the file is not currently mounted on the local host, tt_net- file_file() constructs a pathname of the form: /mountpoint/host/filepath where mountpoint is the mount point pathname in the environment vari- able DTMOUNTPOINT, or /net if the variable is null or unset. The netfilename argument is a copy of a null-terminated string returned by tt_netfile_file(3) or tt_host_netfile_file(3). RETURN VALUE Upon successful completion, the tt_netfile_file() function returns a null-terminated local filename; otherwise, it returns an error pointer. The application can use tt_ptr_error(3) to extract one of the following Tt_status values from the returned pointer: TT_ERR_NETFILE The netfilename argument is not a valid netfilename. APPLICATION USAGE The tt_file_netfile(3), tt_netfile_file(3), tt_host_file_netfile(3) and tt_host_netfile_file(3) functions allow an application to determine a path valid on remote hosts, perhaps for purposes of constructing a com- mand string valid for remote execution on that host. By composing the two calls, paths for files not accessible from the current host can be constructed. For example, if path /sample/file is valid on host A, a program running on host B can use tt_host_netfile_file("C", tt_host_file_netfile("A", "/sample/file")) to determine a path to the same file valid on host C, if such a path is possible. The netfilename string input to tt_netfile_file() should be considered opaque; the content and format of the strings are not a public inter- face. These strings can be safely copied (with strcpy(3C) or similar methods), written to files, or transmitted to other processes, perhaps on other hosts. The mountpoint value is intended to be the mount point for the auto- mounter's host map on those systems supporting automounting services. Allocated strings should be freed using either tt_free(3) or tt_release(3). The tt_open(3) function need not be called before tt_netfile_file().
