The return value of main() shows how the program exited.
Fatal error: Can't use function return value in write context.
The return value for main should indicate how the program exited.
The I have another function B, calling A but not using the return value:.
You could use a return value, or pass a StringBuffer instead.
Normal exit is generally represented by a 0 return value from main.
Return value 0 usually means OK in most operating systems(the ones I can think of anyway).
Alternatively, the main and wmain functions can be declared as returning void(no return value).
Since the return value from A is not needed, there's no need to await the task at the call site.
That is enough, because the method then modifies the array element, and by convention you're expecting element 0 to contain the return value.
The return value can be used by the operating system to check how the program was closed.
In C89(and hence in Microsoft C), there is nostatement about what happens if the main() function returns but does not specify a return value;
Functions cannot return values of type text, ntext, image& timestamps where as procedures can.
The workflow isalready asynchronous, and as you note, it makes no difference to A what you do with its return value after it returns; .
The function's return value will automatically be the result of that expression(you don't use an explicit return). .
If other functionsmake it out of the closure/scope in which they are defined(for instance as return values), those will continue to reference that closure.
You always need to error check the return value of functions which are trying to allocate a resource and may fail:.
In a shell it goes into a shell variable, and if you are running yourprogram form a shell and not using that variable then you need not worry about the return value of main().
However, using this return value is legacy and should be avoided because future versions of React may render components asynchronously in some cases.
A return statement in main has the effect of leaving the main function(destroying any objects with automatic storage duration)and calling std::exit with the return value as the argument.
Since the return value from A is not needed, there's no need to await the task at the call site, as long as someone up the chain awaits it(which happens in C).
Obviously you can do this in other ways, such as structuring your code so this isn't necessary,or constructing a class that can contain the return value or allow it to be set.
If the return value is zero it means that the execution was successful while any non-zero value will represent that something went bad in the execution.
If you really have issues related to efficiency of returning an integer from a process,you should probably avoid to call that process so many times that this return value becomes an issue.
I was under the impression thatstandard specifies that main doesn't need a return value as a successful return was OS based(zero in one could be either a success or a failure in another), therefore the absence of return was a cue for the compiler to insert the successful return itself.
The ERR trap is not executed if the failed command is part of the command list immediately following a while or until keyword, part of the test in an if statement, part of a command executed in a&& or|| list,or if the command's return value is being inverted via!
