SYNOPSIS
THR TSA #include <pthread.h>
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);DESCRIPTION
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.
RETURN VALUE
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.
ERRORS
The pthread_attr_setstacksize() function shall fail if:
[EINVAL] | The value of stacksize is less than {PTHREAD_STACK_MIN} or exceeds a system-imposed limit. |
These functions shall not return an error code of [EINTR].
