c - Why casting NULL to a struct pointer? -

-

इस फ़ंक्शन में: 

  omapi_object_t * inner; यदि (वस्तु) {waiter = (omapi_waiter_object_t *) 0; ....   
  0  को एक  omapi_waiter_object_t  पॉइंटर के लिए उद्धृत किया जा रहा है। उद्देश्य क्या है?  
 मुझे पता है कि एक समान प्रश्न मौजूद है:, लेकिन इसका जवाब मैक्रो का उपयोग करने की वैधता के बारे में है। मेरे मामले में, कोई मैक्रो शामिल नहीं है मैं जानना चाहता हूं कि ऐसा क्यों किया जाता है।   
 
 
 कभी-कभी लोग बस बेकार कोड लिखते हैं।  
 वास्तव में कलाकारों को लिखने में कोई मतलब नहीं है।

php - proc_open Too many open files in long running Symfony Console app -

-
I have created a console app with a SIM console console component. It was going to run for 5 hours but after running 2 hours I have a proc_open (): Many open files in the pipeline error Symfony \ Component \ Console \ Application.php On-line 985. I tried to gc_collect_cycles in my code, but got the same error. Is this a Symphonic Console component bug or should I not run any app for this long time (but I have to)? This problem relates to: Obviously you have many resources in your app It's not a symphony console bug, but it's a PHP bug. You can modify your program by using another programming language to open fewer files.

Example I tried to leave and take (using LINQ), but what I actually see for it Also want to use the automatic filter of the grid.
