pthread_attr_getstacksize, pthread_attr_setstacksize - get and set the stacksize attribute
int pthread_attr_getstacksize(const pthread_attr_t *restrict
attr, size_t *restrict stacksize);
int pthread_attr_setstacksize(pthread_attr_t *attr, size_t stacksize);
The pthread_attr_getstacksize and pthread_attr_setstacksize functions, respectively, shall get and set the thread creation stacksize attribute in the attr object.
The stacksize attribute shall define the minimum stack size (in bytes) allocated for the created threads stack.
Pthreads-w32 defines _POSIX_THREAD_ATTR_STACKSIZE in pthread.h to indicate that these routines are implemented and may be used to set or get the stack size.
Default value: 0 (in Pthreads-w32 a value of 0 means the stack will grow as required)
Upon successful completion, pthread_attr_getstacksize and pthread_attr_setstacksize shall return a value of 0; otherwise, an error number shall be returned to indicate the error.
The pthread_attr_getstacksize function stores the stacksize attribute value in stacksize if successful.
The pthread_attr_setstacksize function shall fail if:
These functions shall not return an error code of [EINTR].
