write() and send() solving errors => difference?

你说的曾经没有我的故事 提交于 2019-12-05 17:27:38
could be any difference in solving errors between this two functions?: To this question brought me another question ... is number of characters always same as number of bytes? For more info: I use it in C on Linux for TCP socket comunication(sys/socket.h) Thanks for your responses. send() write() Return: write(): On success, the number of bytes written are returned (zero indicates nothing was written). On error, -1 is returned, and errno is set appropriately. If count is zero and the file descriptor refers to a regular file, 0 will be returned without causing any other effect. For a special

Android: Sharing (something) via Intent.ACTION_SEND, then automatically return to my app

我的梦境 提交于 2019-12-05 11:55:05
I would like to share something from my application. Once it is shared (e.g - message sent), I want my application to be active again and the sending app to disappear. Using the code below, I expected onActivityResult to be called, but it is never called. After sending email, my application appears again, but after sending SMS ('Messaging') the messaging app remains. ( onActivityResult is never called) Thanks :-) Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND); sharingIntent.setType("text/plain"); String shareBody = "This is a test"; sharingIntent.putExtra(android.content

mpi4py hangs when trying to send large data

久未见 提交于 2019-12-05 09:55:00
i've recently encountered a problem trying to share large data among several processors using the command 'send' from the mpi4py-library. Even a 1000x3 numpy float array is too large to be sent. Any ideas how to overcome this problem? thx in advance. I've found a simple solution. Divide data into small enough chunks... I encountered this same problem with Isend (not with Send ). It appears that the problem was due to the sending process terminating before the receiver had received the data. I fixed this by including a comm.barrier() call at the end of each of the processes. Point-to-point send

When a Facebook user sends the Send dialog within an application, can the application track the recipients?

When users open a Send dialog (e.g. http://www.facebook.com/dialog/send?app_id=123050457758183&name=People%20Argue%20Just%20to%20Win&link=http://www.nytimes.com/2011/06/15/arts/people-argue-just-to-win-scholars-assert.html&redirect_uri=http://www.example.com/response ) they can add or remove people from the To: line. Is there a way for the application to track who was in the To: line if and when the user actually pushes Send? Thanks very much! Nick No. At least not currently... If you look at the official documentation: https://developers.facebook.com/docs/reference/dialogs/send/ then you can

Ajax > onreadystatechange - open/send > order totally arbitrary?

喜欢而已 提交于 2019-12-05 02:16:53
问题 I have a little 'incidental' question: When sending a request with Ajax ... open has to antecede send , for sure... but what about the onreadystatechange allocation? Logically set before open -ing the Request object, after send -ing or in between? To get'em back'n'ya mind: // Using POST XMLHttp.open('POST', url, true); XMLHttp.onreadystatechange = RequestState; XMLHttp.send(parameter); 回答1: Generally speaking, if the only readyState that you care about is 4, then it doesn't really make a

MPI - Sending segments of an array

情到浓时终转凉″ 提交于 2019-12-05 01:13:09
问题 So I have an array of doubles. I would like to send, say every 5th double, to the receiving process. So essentially, I need a way of sending specific doubles with strides between them. Is there a function to do this, apart from storing the doubles into a send buffer? Would it be better to make my own derived type? 回答1: You should definitely create an MPI data type; it gives the MPI library an opportunity to avoid the extra copy for marshaling from the array, and it's pretty straightforward to

Ajax send the data, but php doesn't recieve

我是研究僧i 提交于 2019-12-04 23:26:50
Although I'm still reading Nicholas C. Zakas' book (read over 300 pages within 4 days), in the meantime I got a little project to create a half-automatized documentation generator page for our later big project. It's half-done, but now I want to give more features to it which requires that I need to send the values of textareas to PHP, so PHP can update the mysql and vica versa, but that's not the matter now. The problem: Ajax succeed, I get the success message, but PHP doesn't read the POST. Why? I made my research, I read tones of stackoverflow topics and other websites, phpmanual, w3school
