I've written a program to test malloc() function of musl. But.. 1. Can I use standart rand() and srand() functions to generate random size of allocated memory chunks, or I must to write another one random number generator? 2. Write a program which loops many times allocating and freeing memory So, when my program must to free memory? If it freeing just after its allocating, it always gets one chunk of memory. And how to define maximum size of memory chunk? I define it as MAX_SIZE / 1000, where MAX_SIZE is a maximum total allocated amount (about 8 * 10^8). Is it correctly? 3. I decided to generate a fragmentation diagram as a .dat file for plotting by gnuplot. Are you satisfied with it, or maybe write it as a simple text file with pseudo-graphic diagram? Thanks. I await your reply. UPD. I'm sorry for mixed tho threads, its really bad. -- Sincerely yours, JIghtuse. Content of type "text/html" skipped
