局部变量，全局变量？探寻程序上面的栈（STACK）空间的最大值！

#include 

static long STACK_BLOCK_HEADER;

void depleteStackSpace() {
// declare local variable for booking some STACK spaces.
int intVarInStackSpace = 0;
// output the memory offset
printf("%3.1fM/n", (STACK_BLOCK_HEADER - (long)(&intVarInStackSpace)*1.0)/(1024*1024));
// self recursive
depleteStackSpace();
}

int main() {
// the first local variable in application memory.
int intVarInStackSpace = 0;
// get first local variable address as the STACK block header
STACK_BLOCK_HEADER = (long)(&intVarInStackSpace);
// perform depletion
depleteStackSpace();
// out the normal exit message
printf("normal exit./n");
}
