pthread_attr_getstacksize(3C) Standard C Library Functions 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_getstacksize(), respectively, set and get the thread creation stacksize
attribute in the attr object.
The stacksize attribute defines the minimum stack size (in bytes) allocated 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_getstacksize() 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.
