Description
The alt_fs_reg() function registers a file system with the HAL. After it is registered, a file system can be
accessed using the standard I/O functions.
For more information, refer to the "Developing Programs Using the Hardware Abstraction Layer" section.
System behavior is undefined in the event that a file system is registered with a name that conflicts with an
existing device or file system.
alt_fs_reg() is not thread-safe if other threads are using the device list at the time that alt_fs_reg() is
called. Call alt_fs_reg() only in the following circumstances:
• When running in single-threaded mode.
• From a device initialization function called by alt_sys_init(). alt_sys_init() may only be called
by the single-threaded C startup code.
Return
The return value is zero upon success. A negative return value indicates failure.
