Manual Section... (3) - page: pthread_attr_setstacksize
NAMEpthread_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(pthread_attr_t *attr, size_t *stacksize); Compile and link with -pthread.
DESCRIPTIONThe 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.
RETURN VALUEOn success, these functions return 0; on error, they return a nonzero error number.
ERRORSpthread_attr_setstacksize() can fail with the following error:
- The stack size is less than PTHREAD_STACK_MIN (16384) bytes.
VERSIONSThese functions are provided by glibc since version 2.1.
NOTESFor 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.
BUGSAs at glibc 2.8, if the specified stacksize is not a multiple of STACK_ALIGN (16 bytes on most architectures), it may be rounded downwards, in violation of POSIX.1-2001, which says that the allocated stack will be at least stacksize bytes.
