pthread_attr_setstacksize()

Set thread stack size attribute

Synopsis:

#include <pthread.h>

int pthread_attr_setstacksize( pthread_attr_t * attr,
                               size_t stacksize );

Library:

libc

Description:

The pthread_attr_setstacksize() function sets the thread stack size attribute in the thread attribute object attr to stacksize. The default and minimum value of the thread stack size attribute is PTHREAD_STACK_MIN.

Returns:

EOK

Success.

EINVAL

The value of stacksize is less than PTHREAD_STACK_MIN or greater than the system limit.

Classification:

POSIX 1003.1 (Threads)

Caveats:

The QNX interpretation of PTHREAD_STACK_MIN is enough memory to run a thread that does nothing:

void nothingthread( void )
{
    return;
}
