Removing substring from string before calling strtok in C -

-

I have a variable that I would like to divide into an array of paths: 

  PATH = / bin: / usr / bin: / usr / local / bin   
 The result of the above string would be:  
  [0] -> ; / Bin [1] - & gt; / Usr / bin [2] - & gt; / Usr / local / bin   
 If I call  strtok  on the string with only the delimiter :  then I get the result:  
  [0] - & gt; Path = / bin [1] - & gt; / Usr / bin [2] - & gt; / Usr / local / bin   
 But still I have a substrings in the index before the  PATH =  array. I need to find a way to remove the string from  PATH =  before calling on  strtok .  
 Rather than relocating a new array of four instead of  PATH =  substring, I thought I had the four signals after  PATH =  I can increase the first letter to indicate.  
  four prefix [] = "path ="; If (strstr (str, prefix)) {str + = strlen (prefix); }   
 So now the indicator SR points before / after  PATH = .    Line  str + = after strlen (prefix) :  
  path = / bin: / usr / bin: / usr / local / bin a ????   
 and I get the following array of paths from  strtok .  
  [0] - & gt; / Bin [1] - & gt; / Usr / bin [2] - & gt; / Usr / local / bin   
 Will this be considered bad behavior in C? Is there any side effects from doing this? Do I want another approach: I. E. Assign a new buffer and copy the value of the str in the new buffer without  PATH = .  
 
  
 
 
 call  strtok ()  with  "="  first call the delimiter, then call with "code:": ") Then you can change the delimiter on each call to  strtok ()  if it does need to.  
 Of course, it assumes that you  strtok)  travels your string in the first place. Make sure you are working on a copy of your PATH variable.  
 The offer you offer also works fine too. I saw that the only hold is, if  str  is the only indicator to start the dynamically assigned space, you can not free up space (memory leak) for a long time. Do you need to decide that this is a problem? And if so, the solution is simple: keep a copy of the pointer which needs to be free so that you can clear it.  
 Also keep in mind that PATH is really weird:  
  pat =: / usr / bin :: / bin:   
 Three 'inherent' .  elements are: first : , middle of the middle, and after the last one. Obviously, you usually do not have three at a time, but you need to know the rules of the game.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
