pthread_create空间不足 [英] pthread_create not enough space

问题描述

我在Windows上的MinGW中使用Pthreads.调用pthread_create返回一个错误，该错误翻译为空间不足".它指的是哪种空间?是线程堆栈空间吗?

I'm using Pthreads with MinGW on Windows. A call to pthread_create returns a error which translates to "Not enough space". What kind of space does it refer to? Is the thread stack space?

int scannerThreadReturnValue = pthread_create(&parserThreadHandle, &attr, parserThread, (void *)filename);
    if(scannerThreadReturnValue != 0) {
        printf("Unable to create thread %s\n", strerror(errno));
    }
    else printf("Parser thread creation successfull\n");

推荐答案

错误消息很可能是错误的，因为pthread_*函数家族未设置errno.错误代码由函数返回.

The error message most propably is wrong, as the pthread_* family of functions does not set errno. The error code is returned by the functions.

因此，您对代码的编码如下:

So mod you code like this:

int scannerThreadReturnValue = pthread_create(&parserThreadHandle, &attr, parserThread, (void*)filename);
if (scannerThreadReturnValue != 0)
{
  printf("Unable to create thread: %s\n", strerror(scannerThreadReturnValue));
}
else 
{
  printf("Parser thread creation successful.\n");
}

这将为您提供正确的错误消息.

This will give you the correct error message.
