    NAME

    pthread_attr_getstackaddr, pthread_attr_setstackaddr - get and set
    the stackaddr attribute
     
    

    SYNOPSIS

    #include <pthread.h>

    int pthread_attr_getstackaddr(const pthread_attr_t *restrict attr,
           void **restrict
    stackaddr);
    int pthread_attr_setstackaddr(pthread_attr_t *
    attr, void *stackaddr);
     

    DESCRIPTION

    The pthread_attr_getstackaddr() and pthread_attr_setstackaddr() functions, respectively, shall get and set the thread creation stackaddr attribute in the attr object.

    The stackaddr attribute specifies the location of storage to be used for the created thread's stack. The size of the storage shall be at least {PTHREAD_STACK_MIN}.  

    RETURN VALUE

    Upon successful completion, pthread_attr_getstackaddr() and pthread_attr_setstackaddr() shall return a value of 0; otherwise, an error number shall be returned to indicate the error.

    The pthread_attr_getstackaddr() function stores the stackaddr attribute value in stackaddr if successful.  

    ERRORS

    No errors are defined.

    These functions shall not return an error code of [EINTR].

    The following sections are informative.  

    EXAMPLES

    None.  

    APPLICATION USAGE

    The specification of the stackaddr attribute presents several ambiguities that make portable use of these interfaces impossible. The description of the single address parameter as a "stack" does not specify a particular relationship between the address and the "stack" implied by that address. For example, the address may be taken as the low memory address of a buffer intended for use as a stack, or it may be taken as the address to be used as the initial stack pointer register value for the new thread. These two are not the same except for a machine on which the stack grows "up" from low memory to high, and on which a "push" operation first stores the value in memory and then increments the stack pointer register. Further, on a machine where the stack grows "down" from high memory to low, interpretation of the address as the "low memory" address requires a determination of the intended size of the stack. IEEE Std 1003.1-2001 has introduced the new interfaces pthread_attr_setstack() and pthread_attr_getstack() to resolve these ambiguities.  

    RATIONALE

    None.  

    FUTURE DIRECTIONS

    None.
