I don't think there's a standard function for this.

On some platforms, the maximum filename length varies according to the
location on the disk. If you run UNIX with different filesystems mounted
in various locations on your directory tree, you might see the following
values for the maximum filename length in those locations:

    >>> import statvfs, os
    >>> os.statvfs('/')[statvfs.F_NAMEMAX]
    4032
    >>> os.statvfs('/boot')[statvfs.F_NAMEMAX]
    255
