Use .BR pthread_attr_setstack (3) and .BR pthread_attr_getstack (3) instead. The .BR pthread_attr_setstackaddr () function sets the stack address attribute of the thread attributes object referred to by .I attr to the value specified in .IR stackaddr . This attribute specifies the location of the stack that should be used by a thread that is created using the thread attributes object .IR attr . .I stackaddr should point to a buffer of at least .B PTHREAD_STACK_MIN bytes that was allocated by the caller. The pages of the allocated buffer should be both readable and writable. The .BR pthread_attr_getstackaddr () function returns the stack address attribute of the thread attributes object referred to by .I attr in the buffer pointed to by .IR stackaddr . .SH RETURN VALUE On success, these functions return 0; on error, they return a non-zero error number. .SH ERRORS No errors are defined (but applications should nevertheless handle a possible error return). .SH VERSIONS These functions are provided by glibc since version 2.1. .SH CONFORMING TO POSIX.1-2001 specifies these functions but marks them as obsolete. POSIX.1-2008 removes the specification of these functions. .SH NOTES .I 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, .I stackaddr specifies the next address past the .I highest address of the allocated stack area. However, on architectures with stack that grows upwards, .I stackaddr specifies the .I lowest address in the allocated stack area. By contrast, the .I stackaddr used by .BR pthread_attr_setstack (3) and .BR pthread_attr_getstack (3), is always a pointer to the lowest address in the allocated stack area (and the .I stacksize argument specifies the range of the stack). .SH SEE ALSO .BR pthread_attr_init (3), .BR pthread_attr_setstack (3), .BR pthread_attr_setstacksize (3), .BR pthread_create (3), .BR pthreads (7) -- To unsubscribe from this list: send the line "unsubscribe linux-man" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
