pthread_attr_setstacklazy()

Set the thread lazy-stack attribute

Synopsis:

#include <pthread.h>

int pthread_attr_setstacklazy(
                    pthread_attr_t * attr,
                    int lazystack );

Arguments:

attr

A pointer to the pthread_attr_t structure that defines the attributes to use when creating new threads. For more information, see pthread_attr_init().

lazystack

One of:

• 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 they're unable to allocate stack memory. We recommend that you set the stack size as well, because the default stack size is probably much larger than you really need.

Library:

libc

Use the -l c option to qcc to link against this library. This library is usually included automatically.

Description:

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

Returns:

EOK

Success.

EINVAL

The thread-attribute object that attr points to is invalid.
