+ * Function:	H5FD_supports_swmr_test()
+ *
+ * Purpose:	    Determines if a VFD supports SWMR.
+ *
+ *              The function determines SWMR support by inspecting the
+ *              HDF5_DRIVER environment variable, not by checking the
+ *              VFD feature flags (which do not exist until the driver
+ *              is instantiated).
+ *
+ *              See test/Makefile.am for a list of the VFD strings.
+ *
+ *              This function is only intended for use in the test code.
+ *
+ * Return:	    TRUE (1) if the VFD supports SWMR I/O or vfd_name is
+ *              NULL or the empty string (which implies the default VFD).
+ *
+ *              FALSE (0) if it does not
+ *
+ *              This function cannot fail at this time so there is no
+ *              error return value.
