The prototype for pthread_create function is like this:-
int pthread_create(pthread_t *thread,pthread_attr_t *attr,void *(*start routine),void *arg);
Q.1 .Why the return type of the start_routine must be void*??
Q.2. Why should we pass arg by converting into void * only ??

pthread_attr_set_getstackaddr
PTHREAD_ATTR(3) BSD Library Functions Manual PTHREAD_ATTR(3)
NAME
pthread_attr_getstackaddr, pthread_attr_setstackaddr -- thread attribute operations
SYNOPSIS
#include <pthread.h>
int
pthread_attr_getstackaddr(const pthread_attr_t *restrict attr, void **restrict stackaddr);
int
pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr);
DESCRIPTION
Thread attributes are used to specify parameters to pthread_create(). One attribute object can be used in multiple calls to
pthread_create(), with or without modifications between calls.
The functions pthread_attr_setstackaddr() and pthread_attr_getstackaddr() respectively, set and get the address at which the stack of the
newly created thread should be located. The stackaddr attribute is set within the attr argument, which can subsequently be used as an argu-
ment to pthread_create().
RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error. pthread_attr_getstackaddr() returns
the stackaddr attribute value in stackaddr if successful.
ERRORS
pthread_attr_setstackaddr() will fail if:
[EINVAL] Invalid value for attr.
pthread_attr_getstackaddr() will fail if:
[EINVAL] Invalid value for attr.
SEE ALSO
pthread_create(3), pthread_attr_init(3), pthread_attr_setdetachstate(3), pthread_attr_setstacksize(3)

pthread_attr_setstackaddr(), pthread_attr_getstackaddr(), conform to ISO/IEC 9945-1:1996 (``POSIX.1'')
