NAME
pthread_attr_getstacksize
pthread_attr_setstacksize —
get and set the stacksize attribute
SYNOPSIS
[THR
TSS]
#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 may fail if:
- [EINVAL]
- The value specified by attr does not refer to an initialized thread attribute object.
These functions shall not return an error code of [EINTR].
EXAMPLES
None.
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
None.

CHANGE HISTORY
First released in Issue 5. Included for alignment with the POSIX Threads Extension.
Issue 6
The pthread_attr_getstacksize () and
pthread_attr_setstacksize () functions are marked as part
of the Threads and Thread Stack Size Attribute options.
The
restrict keyword
is added to the pthread_attr_getstacksize ()
prototype for alignment with the ISO/IEC 9899:1999
(“ISO C99”) standard.
IEEE Std 1003.1-2001 (“POSIX.1”)/Cor 1-2002, item XSH/TC1/D6/43 is applied, correcting the margin code in the SYNOPSIS from TSA to TSS and updating the CHANGE HISTORY from ``Thread Stack Address Attribute'' option to ``Thread Stack Size Attribute'' option.
IEEE Std 1003.1-2001 (“POSIX.1”)/Cor 2-2004, item XSH/TC2/D6/87 is applied, updating the ERRORS section to include optional errors for the case when attr refers to an uninitialized thread attribute object.
