PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond- ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. NAME
pthread_attr_getstacksize, pthread_attr_setstacksize - get and set the stacksize attribute SYNOPSIS
#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 num- ber 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]. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
None. RATIONALE
None. FUTURE DIRECTIONS

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. ATTRIBUTES
