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 speci-
fied in stacksize.
The stack size attribute determines the minimum size (in bytes) that
will be allocated for threads created using the thread attributes
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
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_cre-
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
As at glibc 2.8, if the specified stacksize is not a multiple of
