PTHREAD_ATTR_GETSTACKSIZE(3C)PTHREAD_ATTR_GETSTACKSIZE(3C)NAME
pthread_attr_getstacksize, pthread_attr_setstacksize - get or set
stacksize attribute
SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ]
#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 functions pthread_attr_setstacksize() and pthread_attr_getstack‐
size(), respectively, set and get the thread creation stacksize
attribute in the attr object.
The stacksize attribute defines the minimum stack size (in bytes) allo‐
cated for the created threads stack. When the stacksize argument is
NULL, the default stack size becomes 1 megabyte for 32-bit processes
and 2 megabytes for 64-bit processes.
RETURN VALUES
Upon successful completion, pthread_attr_setstacksize() and
pthread_attr_getstacksize() return a value of 0. Otherwise, an error
number is returned to indicate the error. The pthread_attr_getstack‐
size() function stores the stacksize attribute value in stacksize if
successful.
ERRORS
The pthread_attr_setstacksize() or pthread_attr_getstacksize() function
may fail if:
EINVAL
attr or stacksize is invalid.
