PTHREAD_ATTR_SETSTACKSIZE(3)nux Programmer's ManualREAD_ATTR_SETSTACKSIZE(3)
pthread_attr_setstacksize, pthread_attr_getstacksize - set/get stack
size attribute in thread attributes object
#include <pthread.h>
int pthread_attr_setstacksize(pthread_attr_t *attr, size_t stacksize);
int pthread_attr_getstacksize(const pthread_attr_t *attr, size_t *stacksize);
Compile and link with -pthread.
The pthread_attr_setstacksize() function sets the stack size
attribute of the thread attributes object referred to by attr to the
value specified in stacksize.
The stack size attribute determines the minimum size (in bytes) that
will be allocated for threads created using the thread attributes
object attr.
The pthread_attr_getstacksize() function returns the stack size
attribute of the thread attributes object referred to by attr in the
buffer pointed to by stacksize.
On success, these functions return 0; on error, they return a nonzero
error number.
pthread_attr_setstacksize() can fail with the following error:
EINVAL The stack size is less than PTHREAD_STACK_MIN (16384) bytes.
On some systems, pthread_attr_setstacksize() can fail with the error
EINVAL if stacksize is not a multiple of the system page size.
These functions are provided by glibc since version 2.1.
For an explanation of the terms used in this section, see

POSIX.1-2001, POSIX.1-2008.
For details on the default stack size of new threads, see
pthread_create(3).
A thread's stack size is fixed at the time of thread creation. Only
the main thread can dynamically grow its stack.
The pthread_attr_setstack(3) function allows an application to set
both the size and location of a caller-allocated stack that is to be
used by a thread.
As at glibc 2.8, if the specified stacksize is not a multiple of
STACK_ALIGN (16 bytes on most architectures), it may be rounded
downward, in violation of POSIX.1, which says that the allocated
stack will be at least stacksize bytes.
