Blocks in C, not C++Blocks in C, not C++Posted Sep 16, 2009 21:54 UTC (Wed) by ncm (subscriber, #165)In reply to: Blocks in C, not C++ by atai Parent article: Tornado and Grand Central Dispatch: a quick look
If you're asking whether this "blocks" feature will be added to the Gcc C compiler, I would expect not until it gets very close to standardization as an ISO C feature. I don't know if Apple has placed this blocks thing before the C committee yet, or what the C committee thinks/would think of it. The GNU Gcc developers are very keen on observing relevant standards; proprietary features encourage lock-in. I doubt anybody would bother putting it in before that, given that the Clang C compiler has it.

I will note further that the Lambda feature in C++ has different syntax from Blocks, and there will be strong pressure, particularly from implementers, on the C committee to match the C++ Lambda syntax, i.e. using "[]" where Apple's Blocks uses "^". (Ironically, "[]" looks typographically more like a block, and "^" looks more like a lambda.) I expect Apple to support both syntaxes in the end.

But [] is used by objective C to call methods, so Apple is likely to not support this, at least not OS
X's most-supported language.

Here is a list of non-standard GCC extensions:

You can probably find a better list; this one took me only 15 seconds to find.
