PTHREAD_ATTR_SETSTACKSIZE(3P)        SysV        PTHREAD_ATTR_SETSTACKSIZE(3P)



NAME
     pthread_attr_setstacksize - Sets the value of the stack size attribute of
     a thread attributes object

SYNOPSIS
     #include <pthread.h>

     int pthread_attr_setstacksize (attr, stacksize)
     pthread_attr_t *attr;
     long stacksize;

DESCRIPTION
     The pthread_attr_setstacksize function sets the thread stack size
     attribute.  The stack size attribute specifies the minimum number of
     bytes allocated to the thread when it is created.  The default stack size
     is the maximum stack size allowed on your system.

     The attr argument specifies the address of the thread attributes object
     to be modified; stacksize specifies the new value for the stack size
     attribute (in bytes).

NOTES
     This interface is based on draft 4 of the IEEE P1003.4a standard, and
     will be changed to conform to the final version.

DIAGNOSTICS
     Upon successful completion, a value of 0 (zero) is returned.  Otherwise,
     -1 is returned and errno is set to indicate the error.

ERRORS
     If the pthread_attr_setstacksize function fails, errno may be set to the
     following value:

     [EINVAL]  The value specified by the attr or stacksize argument is
               invalid.
