    NAME

    pthread_attr_setstackaddr, pthread_attr_getstackaddr -
    set/get stack address attribute in thread attributes object
     
    

    SYNOPSIS

    #include <pthread.h>
    
    int pthread_attr_setstackaddr(pthread_attr_t *attr, void *stackaddr);
    int pthread_attr_getstackaddr(pthread_attr_t *attr, void **stackaddr);
    
    Compile and link with -pthread.
    
     

    DESCRIPTION

    These functions are obsolete: do not use them. Use pthread_attr_setstack(3) and pthread_attr_getstack(3) instead.

    The pthread_attr_setstackaddr() function sets the stack address attribute of the thread attributes object referred to by attr to the value specified in stackaddr. This attribute specifies the location of the stack that should be used by a thread that is created using the thread attributes object attr.

    stackaddr should point to a buffer of at least PTHREAD_STACK_MIN bytes that was allocated by the caller. The pages of the allocated buffer should be both readable and writable.

    The pthread_attr_getstackaddr() function returns the stack address attribute of the thread attributes object referred to by attr in the buffer pointed to by stackaddr.  

    RETURN VALUE

    On success, these functions return 0; on error, they return a non-zero error number.  

    ERRORS

    No errors are defined (but applications should nevertheless handle a possible error return).  

    VERSIONS

    These functions are provided by glibc since version 2.1.  

    CONFORMING TO

    POSIX.1-2001 specifies these functions but marks them as obsolete. POSIX.1-2008 removes the specification of these functions.  

    NOTES

    Do not use these functions! They cannot be portably used, since they provide no way of specifying the direction of growth or the range of the stack. For example, on architectures with a stack that grows downwards, stackaddr specifies the next address past the highest address of the allocated stack area. However, on architectures with stack that grows upwards, stackaddr specifies the lowest address in the allocated stack area. By contrast, the stackaddr used by pthread_attr_setstack(3) and pthread_attr_getstack(3), is always a pointer to the lowest address in the allocated stack area (and the stacksize argument specifies the range of the stack).
