cstacksize

What is the stack size on Cygwin/Windows 64bit?

How to increase stack size and similar? I want to know the stack size on Cygwin 64 bit for windows. I'm programming with C on netbeans and i tried to make a stack overflow to find the answer. From the code I obtained 43104 as result... Now, what this number is? bit-Kb-Mb? Sorry for my english :)

Solution

  • Since you are using cygwin this is very easy with getrlimit

    #include <stdio.h>
#include <sys/resource.h>
#include <sys/time.h>

int
main(void)
{
    struct rlimit rl;

    if (getrlimit(RLIMIT_STACK, &rl) != 0)
        return -1;
    fprintf(stdout, "current: %ld kB\n\n", rl.rlim_cur / 1024);

    return 0;
}
