RTEMS POSIX API User's Guide
A pathname is a string that consists of no more than PATH_MAX
bytes, including the terminating null character. A pathname has an optional
beginning slash, followed by zero or more filenames separated by slashes.
If the pathname refers to a directory, it may also have one or more trailing
slashes. Multiple successive slahes are considered to be the same as
one slash.
POSIX allows a pathname that begins with precisely two successive slashes to be interpreted in an implementation-defined manner. RTEMS does not currently recognize this as a special condition. Any number of successive slashes is treated the same as a single slash. POSIX requires that an implementation treat more than two leading slashes as a single slash.
