pthread_...stacksize(3) Library Functions Manual pthread_...stacksize(3)
pthread_attr_setstacksize, pthread_attr_getstacksize - set/get
stack size attribute in thread attributes object
POSIX threads library (libpthread, -lpthread)
#include <pthread.h>
int pthread_attr_setstacksize(pthread_attr_t *attr, size_t stacksize);
int pthread_attr_getstacksize(const pthread_attr_t *restrict attr,
size_t *restrict stacksize);
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.
For an explanation of the terms used in this section, see
attributes(7).

These functions are provided since glibc 2.1.
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.
See pthread_create(3).
