c - How could this happen when reading a socket with a error ENOMEM return -


error How can this be done when reading socket with ENOMEM returns? Man 2 read, I can not find any details about this error, someone can help me thanks. My Linux kernel 2.6.26-1-686

isomom

is an OS error code, As defined in Kern / include / kern / errno.h, which is returned due to inadequate memory

The name is the error no memory for the ENOMEM. One of the error codes returned by the fork () call means that no more storage space is available anymore. They are raised in relation to the socket when there is not enough resources available to make the socket. The value of the error code is 12.

You can handle this error instantly and release all the allocated resources as soon as possible, to avoid the need to allocate new resources.

Edit:

To obtain a data buffer, read the socket due to allocation and need to be free after your requirement. Also make sure that there is sufficient memory to return the error if failing to allocate memory.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
