NAME
       pthread_attr_setstacksize - Changes the stacksize attribute in the specified thread attributes object.

LIBRARY
       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS
       #include <pthread.h>

       int pthread_attr_setstacksize(
		       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 to be modified.  New value for the stacksize attribute of the thread attributes object specified by the attr argu-
       ment.  The stacksize argument must be greater than or equal to PTHREAD_STACK_MIN.  PTHREAD_STACK_MIN specifies the minimum size (in  bytes)
       of stack needed for a thread.

DESCRIPTION
       This  routine  sets the stacksize attribute in the thread attributes object specified by the attr argument.  Use this routine to adjust the
       size of the writable area of the stack for a new thread.

       The size of a thread's stack is fixed at the time of thread creation. Only the initial thread can dynamically extend its stack.

       Many compilers do not check for stack overflow.	Ensure that the new thread's stack is sufficient for the resources  required  by  routines
       that are called from the thread.

RETURN VALUES
       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, or the value specified by  stacksize  is  less  than  PTHREAD_STACK_MIN	or
       exceeds a DECthreads-imposed limit.

ERRORS
       None
