pthread_attr_getstacksize

PTHREAD_ATTR(3) 					   BSD Library Functions Manual 					   PTHREAD_ATTR(3)

NAME

     pthread_attr_getstacksize, pthread_attr_setstacksize -- thread attribute operations

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

     Thread attributes are used to specify parameters to pthread_create().  One attribute object can be used in multiple calls to
     pthread_create(), with or without modifications between calls.

     The functions pthread_attr_setstacksize() and pthread_attr_getstacksize(), respectively, set and get the size of the stack that is to be cre-
     ated for the new thread. The stack size attribute is set within the attr argument, which can subsequently be used as an argument to
     pthread_create().

RETURN VALUES

     If successful, these functions return 0.  Otherwise, an error number is returned to indicate the error.  pthread_attr_getstacksize() returns
     the stacksize attribute value in stacksize if successful.

ERRORS

     pthread_attr_getstacksize() will fail if:

     [EINVAL]		Invalid value for attr.

     pthread_attr_setstacksize() will fail if:

     [EINVAL]		Invalid value for attr.

     [EINVAL]		stacksize is less than PTHREAD_STACK_MIN.

     [EINVAL]		stacksize is not a multiple of the system page size.

SEE ALSO

STANDARDS

     pthread_attr_setstacksize(), pthread_attr_getstacksize() conform to ISO/IEC 9945-1:1996 (``POSIX.1'')
