pthread_attr_setstack (3)
NAME
pthread_attr_setstack, pthread_attr_getstack - set/get stack attributes in thread attributes objectSYNOPSIS
#include <pthread.h>
int pthread_attr_setstack(pthread_attr_t *attr, void *stackaddr, size_t stacksize); int pthread_attr_getstack(const pthread_attr_t *attr, void **stackaddr, size_t *stacksize);
Compile and link with -pthread.

DESCRIPTION
The pthread_attr_setstack() function sets the stack address and stack size attributes of the thread attributes object referred to by attr to the values specified in stackaddr and stacksize, respectively. These attributes specify the location and size of the stack that should be used by a thread that is created using the thread attributes object attr. stackaddr should point to the lowest addressable byte of a buffer of stacksize bytes that was allocated by the caller. The pages of the allocated buffer should be both readable and writable. The pthread_attr_getstack() function returns the stack address and stack size attributes of the thread attributes object referred to by attr in the buffers pointed to by stackaddr and stacksize, respectively.RETURN VALUE
On success, these functions return 0; on error, they return a nonzero error number.ERRORS
pthread_attr_setstack() can fail with the following error:- EINVAL
- stacksize is less than PTHREAD_STACK_MIN (16384) bytes. On some systems, this error may also occur if stackaddr or stackaddr + stacksize is not suitably aligned.
VERSIONS
These functions are provided by glibc since version 2.2.ATTRIBUTES
