pthread_attr_setstacklazy()

Set thread stack attribute

Synopsis:

#include <pthread.h>

int pthread_attr_setstacklazy(
                    pthread_attr_t * attr,
                    int lazystack );

Library:

libc

Description:

The pthread_attr_setstacklazy() function sets the thread stack attribute in the attribute object attr to lazystack.

Possible values for lazystack are:

PTHREAD_STACK_LAZY

Allocate physical memory for the thread stack on demand (the default).

PTHREAD_STACK_NOTLAZY

Allocate physical memory for the whole stack up front. Use this value to ensure that your server processes don't die later on because it's unable to allocate stack memory. We recommend that you set the stack size as well since the default stack size is probably much larger than you really need.

Returns:

EOK

Success.

EINVAL

Invalid thread attribute object attr.

ENOTSUP

Invalid thread inherit scheduling attribute lazystack.

Classification:

QNX 6
