Description:
Blocks Runtime library
Blocks are a proposed extension to the C, Objective C, and C++ languages developed by Apple to support the Grand Central Dispatch concurrency engine. Blocks are anonymous inline functions that automatically capture a read-only copy of local variables, and have read-write access to local variables that are declared with the "__block" storage class. . This package contains a library that is needed by programs that use Blocks.
