NAMEtt_host_file_netfile — map between local and canonical pathnames on a
remote host
SYNOPSIS
#include <Tt/tt_c.h>
char *tt_host_file_netfile(
const char *host,
const char *filename);
DESCRIPTION
The tt_host_file_netfile function performs a conversion equivalent to
that of the tt_file_netfile(3) function, but performs it on a remote
host.
The filename argument is a pathname (absolute or relative) that is
valid on the remote host. Every component of filename must exist,
except for the last component. The host argument is a name of a remote
host.
RETURN VALUE
Upon successful completion, the tt_host_file_netfile function returns a
freshly allocated null-terminated string of unspecified format, which
can be passed to tt_netfile_file(3) or tt_host_netfile_file(3); other‐
wise, 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_PATH
The filename argument is a path that is not valid on the
remote host.
TT_ERR_DBAVAIL
The ToolTalk database server could not be reached on host,
perhaps because the host is unavailable or cannot be reached
through the network.
TT_ERR_DBEXIST
The ToolTalk database server is not properly installed on
host.
TT_ERR_UNIMP
The ToolTalk database server contacted is of a version that
does not support tt_host_file_netfile.
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.
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_host_file_netfile.
