converting void pointer to pthread_t on HPUX Itanium

i am trying to convert void pointer to pthread_t on hpux-itanium 64 bit which fails as below

Code:

"src/file.cpp", line 88: error #2171: invalid type conversion
          pthread_t tid = reinterpret_cast<pthread_t>(m_threadId);

1 error detected in the compilation of "src/file.cpp"

^

m_threadId is of type void *

Any help?

no answer till now???

here is one sample to see the above issue

Code:

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

int main()
{
  int n = 3;
  void *m = (void *)&n;
  //pthread_t p = reinterpret_cast<pthread_t>(m);
  pthread_t p = static_cast<pthread_t>(m);
  return 0;
}

Any help??

pass a pointer-to-pointer, or return a pointer?

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it: (1) one is to pass a pointer-to-pointer parameter, like: int my_malloc(int size, char **pmem) { *pmem=(char *)malloc(size); if(*pmem==NULL)...

LEARN ABOUT LINUX

pthread_equal

PTHREAD_EQUAL(3)					     Linux Programmer's Manual						  PTHREAD_EQUAL(3)

NAME

       pthread_equal - compare thread IDs

SYNOPSIS

       #include <pthread.h>

       int pthread_equal(pthread_t t1, pthread_t t2);

       Compile and link with -pthread.

DESCRIPTION

       The pthread_equal() function compares two thread identifiers.

RETURN VALUE

       If the two thread IDs are equal, pthread_equal() returns a nonzero value; otherwise, it returns 0.

ERRORS

       This function always succeeds.

CONFORMING TO

       POSIX.1-2001.

NOTES

       The  pthread_equal()  function  is  necessary  because thread IDs should be considered opaque: there is no portable way for applications to
       directly compare two pthread_t values.

SEE ALSO

       pthread_create(3), pthread_self(3), pthreads(7)
