Marcel Taeumel uploaded a new version of FFI-Pools to project FFI:
http://source.squeak.org/FFI/FFI-Pools-monty.9.mcz ==================== Summary ==================== Name: FFI-Pools-monty.9 Author: monty Time: 30 March 2018, 2:25:00.511178 am UUID: 22106a09-fd24-0d00-abe7-71ab0f24d7b0 Ancestors: FFI-Pools-monty.8 renamed every FFISharedPool* class to FFIExternalSharedPool to be more descriptive and avoid conflicting with OSSubProcess. Class comments, generated code prefixes, and the program directory name were also modified for consistency =============== Diff against FFI-Pools-monty.6 =============== Item was added: + ----- Method: Boolean class>>ffiExternalSharedPoolGenerateOutputCodeFor:with: (in category '*FFI-Pools') ----- + ffiExternalSharedPoolGenerateOutputCodeFor: aVariableName with: aProgramGenerator + aProgramGenerator emitBooleanOutputCodeFor: aVariableName!
