New features are available so that users of SAS High-Performance Risk can run C libraries in SAS High-Performance Risk that are not thread-safe.

The PROTO procedure contains the following new features:

1. New options in PROC PROTO statement: BRIDGEFILE=<filename> and BRIDGECATCHSIGNALS
   
   You use the BRIDGEFILE= option specify the full pathname of a file to which the PROTO procedure writes C templates.
   
   You use the BRIDGECATCHSIGNALS option to indicate that the C template contains code that installs and handles signals.
   
   
2. New options on the function prototype: BRIDGE
   
   You use the BRIDGE option on a function prototype to notify the PROTO procedure that a function is not thread-safe and that it needs to be called through the bridge component of SAS High-Performance Risk.

1. The function LOADLIBRARY(version, libraryname) loads a shared C library through the bridge component of SAS High-Performance Risk.
2. The function UNLOADLIBRARY(version) unloads the library.
3. The function SETVERSION(version) sets the current library to use by the version number.
