Re: [NSPipe pipe] returning nil (running out of filehandles?)

Just thought I'd add some hard numbers to this thread. My original fixed NSTask based implementation ran in 8 minutes. Using the code below, with a 1k buffer size, runs in 6:15 minutes, so the speedup is about 25%. A 10k buffer took about the same. Boosting the buffer to 1MB actually ran

Re: More fun with C++

There are some hits to using .mm rather than .m files (check the list archives). Nothing major enough to sound any dire warnings though ;-) And sometimes you are adding C++ to an existing Obj-C only project (and I hate renaming every .m file to a .mm file in version control plus the potential los

Re: More fun with C++

No but you include it in a Obj-C++ source file. Rename your obj-c file with a .mm extension. Le 3 avr. 08 à 18:23, Jens Alfke a écrit : On 3 Apr '08, at 9:05 AM, Herb Petschauer wrote: # ifdef __cplusplus extern "C" { # endif That won't help if the header is using C++-only syntax like

Objective-C Instance Variable Names

There is a common practice of prefixing instance variable names with "_", a single underscore character. If Objective-C 2.0 properties are used this would result in dots followed by underscores when invoking accessor methods with the dot syntax. Not a desirable situation. It appears that
