获得linux线程栈的大小


结果是：10485760 B  换算下 恰哈是10MB

编译命令 gcc -lpthread p_stack.c

代码：

#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>

void* thread()
{
  pthread_attr_t pattr;
  size_t size = 0;
  printf("default size:%d\n", size);
  pthread_attr_getstacksize(&pattr, &size);
  printf("current thread stack size:%d\n", size);
  return (void*)0;
}

int main()
{
  pthread_t ptd;
  pthread_create(&ptd, NULL, thread, NULL);
  pthread_join(ptd, NULL);
  printf("main thread quit!\n");
}
