Veritas™ File System 5.0.1 Programmer's Reference Guide

dirp = opendir(".");

readdir_r(dirp, (struct dirent *)&entry, &result);

Note: The usage section of the getcwd(3C) man page states that applications should

exercise care when using the chdir() call in conjunction with getcwd(). The current

working directory is global to all threads within a process. If more than one thread

calls chdir() to change the working directory, a subsequent call to getcwd() could

produce unexpected results.

Querying named data streams

In the following example, a file named_stream_file was created with 20 named

data streams using the API calls.

The named data streams are not displayed by the ls command. When named data

streams are created, they are organized in a hidden directory. For example:

# ls -al named_stream_file

-r-xr-lr-x1 root other 1024 Aug 12 09:49named_stream_file

To query named data streams

■ Use the getdents() or readdir_r() system call to query the named_stream_file

file for its directory contents, which contains the 20 named stream files:
