Returns the value of the stacksize attribute of a thread attributes object.
Threads Library (libpthreads.a)
int pthread_attr_getstacksize ( attr, stacksize)
const pthread_attr_t *attr;
The pthread_attr_getstacksize subroutine returns the value of the stacksize attribute of the thread attributes object attr. This attribute specifies the minimum stack size of a thread created with this attributes object. The value is given in bytes. The default stack size is PTHREAD_STACK_MIN, *12 defined in pthread.h.
Note: The pthread.h header file must be the first included file of each source file using the threads library. Otherwise, the -D_THREAD_SAFE compilation flag should be used, or the cc_r compiler used. In this case, the flag is automatically set.
|attr||Specifies the thread attributes object.|
|stacksize||Points to where the stacksize attribute value will be stored.|
Upon successful completion, the value of the stacksize attribute is returned via the stacksize parameter, and 0 is returned. Otherwise, an error code is returned.
pthread_attr_getstacksize subroutine is unsuccessful if the
following is true:
|EINVAL||The attr or stacksize parameters are not valid.|
This function will not return an error code of [EINTR].
This subroutine is part of the Base Operating System (BOS) Runtime.
The pthread_attr_setstacksize (pthread_attr_setstacksize Subroutine) subroutine, pthread_attr_init (pthread_attr_init Subroutine) subroutine, the pthread.h file.
