Returns the value of the stacksize attribute of a thread attributes object.
Threads Library (libpthreads.a)
#include <pthread.h>
int pthread_attr_getstacksize (attr, stacksize) const pthread_attr_t *attr; size_t *stacksize;
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.
The 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 subroutine, pthread_attr_init subroutine, the pthread.h file.
