For dynamic arrays (malloc or C++ new) you need to store the size of the array as mentioned by others or perhaps build an array manager structure which handles add, remove, count, etc. Unfortunately C doesn't do this nearly as well as C++ since you basically have...
I give the user a summary of the number of rows based on types of data, but I want to make sure that I don't read in too many rows of data and cause OutOfMemoryErrors. Each row translates into an object. Is there a way to find out the size of that object programmatically? ...
You can find the length of each dimension from the array's GetLength method.You can change the length of an individual dimension, which changes the overall size. However, you cannot change the rank (the number of dimensions).See AlsoTasks...
I have an array of "unit type", i use this array as a parameter into a trigger. Now, to loop through it i have to know its size, how can i obtain this information? (let's say i want set an int variable with the size of this array). (since the function im developing must be...
I'm playing around with buffer and heap overflow vulnerabilities, and it is all fine to exploit stuff when you have the source code and can see all the variables, their sizes and values, etc. But, what if I only have the compiled program, and I need to find a size o...
of it's size in memory by the sum of the size of it's members. If your reference type was to contain other reference type members, it's gets dodgy though. Using the resulting byte array to get the size of a reference type isn't a reliable method for measuring the size of a ...
As mentioned above, the OOM is a common indication of a memory leak. Essentially, the error is thrown when there’s insufficient space to allocate a new object. Try as it might, the garbage collector can’t find the necessary space, and the heap can’t be expanded any further. Thus, ...
Memory leak is the gradual loss of available computer memory when a program repeatedly fails to return memory it obtained for temporary use.
Step 2: What to look for? Now that we have a simple picture of the memory in our mind, let's go back to the first picture: I know that, you are going to say: "Hey, it's just a row ofbytes! How to find the memory units?" And then I'll tell you that, you asked the big...
("native heap") just manages memory and does not manage types. It's not possible on that level to distinguish two objects of the same size but different type. If you have a memory leak, you can only give a statement like "I have a leak of n bytes". To find our more about the ...
