pthread_create not enough space

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");

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.

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");
}

This will give you the correct error message.

This is strange, though am not sure about MinGW, Yes it should be referring to the stack size. What kind of application is this ? did you create plenty threads prior to this parserThread ? . In ideal case should not failed in space issue.

Probably you can initiate thread attribute, and try to set stacksize before creating thread. So we can narrow down easily.
