Configuring a Search Path

In the Search Path control panel page, you can configure a search path to allow RTX64 to look in specific directories when you attempt to load an RTSS application or RTDLL. Once a search path is set, you can load applications and RTDLLs by specifying a base filename only, assuming one of the directories in the search path contains the file you want to load.

NOTE: You must be a member of the RTX64Administrators user group to modify the search path. For more information on user groups, see User Groups and Access Permissions.

NOTE: Each directory in the search path must be an absolute path, ending with a forward slash (/).

NOTE: Each directory in the search path must contain less than 253 characters. Note that the characters in the name of a file you try to load via the search path are included in the 253 character limit. A directory and file name combination that exceeds this limit will result in an error.

NOTE: You may experience a delay when you attempt to load an application or RTDLL if your search path contains several directories. Each directory that is added to the search path may result in a longer delay.

NOTE: The order of directories in the search path is important. When the search path is used, the directories within the search path are searched in order, beginning with the first directory and ending with the last.
