问题 I\'ve seen this error with different variations on discussion forums but being a non programmer I\'m not sure how to progress this. Basically I have code which I found to help me with changing the background colors of cells on a grouped uitableview. The code introduced a line as such: CGContextAddArcToPoint(c, minx, miny, midx, miny, ROUND_SIZE); This gave an error indicated that it wasn\'t declared, so I added to my .h file the following under import uikit: #import <UIKit/UIKit.h> #define

What is a thread exit code?

问题 What exactly is a thread exit code in the Output window while debugging? What information it gives me? Is it somehow useful or just an internal stuff which should not bother me? The thread 0x552c has exited with code 259 (0x103). The thread 0x4440 has exited with code 0 (0x0). Is there maybe some sort of list of possible exit codes along with its significance? 回答1: There actually doesn't seem to be a lot of explanation on this subject apparently but the exit codes are supposed to be used to

Return value range of the main function

What does standard say about main return values range? Say only up to 255? Because int main(void){ return 256; } echo $? ; # out 0 Jerry Coffin The standard doesn't say. 0 , EXIT_SUCCESS and EXIT_FAILURE have (sort of) specified meanings. Anything else depends on the implementation. At the present time, most Unix-based systems only support 8-bit return values. Windows supports (at least) a 32-bit return value. I haven't checked whether 64-bit Windows supports a 64-bit return value, but I rather doubt it, since even 64-bit Windows normally still uses a 32-bit int. As others have stated, the C &

问题 I have a trivial console application in .NET. It\'s just a test part of a larger application. I\'d like to specify the \"exit code\" of my console application. How do I do this? 回答1: 3 options: You can return it from Main if you declare your Main method to return int . You can call Environment.Exit(code). You can set the exit code using properties: Environment.ExitCode = -1; . This will be used if nothing else sets the return code or uses one of the other options above). Depending on your

ExitCodes bigger than 255, possible?

阅读更多关于 ExitCodes bigger than 255, possible?

问题 If yes, on which operating system, shell or whatever? Consider the following java program (I\'m using java just as an example, any language would be good for this question, which is more about operation systems): public class ExitCode { public static void main(String args[]) { System.exit(Integer.parseInt(args[0])); } } Running it on Linux and bash, it returns always values less equal 255, e.g. ( echo $? prints the exit code of the previous executed command) > java ExitCode 2; echo $? 2 >

Are there any standard exit status codes in Linux?

阅读更多关于 Are there any standard exit status codes in Linux?

问题 A process is considered to have completed correctly in Linux if its exit status was 0. I\'ve seen that segmentation faults often result in an exit status of 11, though I don\'t know if this is simply the convention where I work (the apps that failed like that have all been internal) or a standard. Are there standard exit codes for processes in Linux? 回答1: 8 bits of the return code and 8 bits of the number of the killing signal are mixed into a single value on the return from wait(2) & co..

问题 I am running a program and want to see what its return code is (since it returns different codes based on different errors). I know in Bash I can do this by running echo $? What do I do when using cmd.exe on Windows? 回答1: A pseudo environment variable named errorlevel stores the exit code: echo Exit Code is %errorlevel% Also, the if command has a special syntax: if errorlevel See if /? for details. Example @echo off my_nify_exe.exe if errorlevel 1 ( echo Failure Reason Given is %errorlevel%
