filename(5) OSS System Calls Reference Manual
a single slash.
An absolute pathname begins with a slash character. An absolute pathname
identifies an OSS file with respect to the current root directory.
A relative pathname does not begin with a slash character. A relative pathname
identifies an OSS file with respect to the current working directory.
The filename_1 parameter specifies a directory. If filename_1 is a single period
character (., called dot), then filename_1 indicates the OSS current working
directory.
If filename_1 is two period characters (.., called dot-dot), then filename_1 indi-
cates the parent directory of the OSS current working directory.
The filename_2 parameter specifies either another directory or the unique
identifier for a file other than a directory within the filename_1 directory. If
filename_2 specifies a directory, then a filename_3 parameter can be specified,
with the same constraints as for filename_2, and so on. The last filename_n
parameter specified must uniquely identify a file that is not a directory.
All filename_n parameters must meet the requirements for the filename parame-
ter.
node_name Specifies the NonStop server node name used by the Expand product for access
to files on other nodes. A node name is a character string of up to seven valid

(Uppercase letters A through Z are accepted but converted to lowercase letters.)
The first character must be a letter. Node names specified in the OSS file system

a character string of up to eight valid characters. Valid characters are the letters
a through z and the digits 0 through 9. (Uppercase letters A through Z are
accepted but converted to lowercase letters.) The first character must be a letter.
file_id Specifies the unique identifier of the file within its subvolume. A file identifier is
a character string of up to eight valid characters. Valid characters are the letters
a through z and the digits 0 through 9. (Uppercase letters A through Z are
accepted but converted to lowercase letters.) The first character must be a letter.
temp_file_id Specifies the unique identifier of the file within its disk volume. A temporary file
identifier is a character string of two to eight valid characters. The first character
