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 stacksize of a thread created with this attributes object. The value is given in bytes. For 32-bit compiled applications, the default stacksize is 96 KB (defined in the pthread.h file). For 64-bit compiled applications, the default stacksize is 192 KB (defined in the pthread.h file).
Item | Description |
---|---|
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].
