PTHREAD_ATTR_SETSTACKSIZE(3) Linux Programmer's Manual PTHREAD_ATTR_SETSTACKSIZE(3)
pthread_attr_setstacksize, pthread_attr_getstacksize - set/get stack size attribute in
thread attributes object
int pthread_attr_setstacksize(pthread_attr_t *attr, size_t stacksize);
int pthread_attr_getstacksize(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 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 loca-
tion 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.1-2001, which says
that the allocated stack will be at least stacksize bytes.
