* \section intro Introduction
*
+ * This is the documentation for the library interface of wimlib 1.2.6. If you
+ * have installed wimlib and want to know how to use the @c imagex program,
+ * please see the man pages instead.
+ *
* wimlib is a C library to read, write, and mount archive files in the Windows
* Imaging Format (WIM files). These files are normally created using the @c
* imagex.exe utility on Windows, but this library provides a free
* message being printed.
*
* wimlib is thread-safe as long as different ::WIMStruct's are used, except for
- * the fact that wimlib_set_print_errors() and wimlib_set_memory_allocator()
- * both apply globally.
+ * the following exceptions:
+ * - wimlib_set_print_errors() and wimlib_set_memory_allocator() both apply globally.
+ * - You also must call wimlib_global_init() in the main thread to avoid any
+ * race conditions with one-time allocations of memory.
+ * - wimlib_mount_image(), while it can be used to mount multiple WIMs
+ * concurrently in the same process, will daemonize the entire process when it
+ * does so for the first time. This includes changing the working directory
+ * to the root directory.
*
* To open an existing WIM, use wimlib_open_wim().
