pthread_attr_getstacksize(3)				     Library Functions Manual				      pthread_attr_getstacksize(3)

NAME

       pthread_attr_getstacksize - Obtains the value of the stacksize attribute in the specified thread attributes object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int pthread_attr_getstacksize(
			const pthread_attr_t  *attr,
			size_t		      *stacksize);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       IEEE Std 1003.1c-1995, POSIX System Application Program Interface

PARAMETERS

       Thread  attributes  object  whose  stacksize attribute is obtained.  Receives the value of the stacksize attribute of the thread attributes
       object specified by the attr argument.

DESCRIPTION

       This routine obtains the stacksize attribute of the thread attributes object specified in the attr argument.

RETURN VALUES

       On successful completion, this routine returns a zero (0) and the stacksize value in the location specified in the stacksize argument.

       If an error condition occurs, this routine returns an integer value indicating the type of error.  Possible return values are  as  follows:
       Successful completion.  The value specified by attr is invalid.

ERRORS

       None

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.
