✔ Appearance ✔ Standard ✔ Console
result& = FN FBTESTFORLIBRARY("Library Name")
July 28, 2000 (Release 3)
This function determines whether a library exists and returns a boolean result. Keep in mind that libraries often have one name that is visible in the Finder and a different name that is used for access. To determine the required name for
LIBRARY statements, use a resource editor like Resorcerer and examine the
_"cfrg" resource. The proper names for many common libraries can be found under the help menu in the manual named "Mac Libraries."
LONG IF FN FBTestForLibrary("ThreadsLib") = _false
