MDK 5.38发布后，AC6的_sys_tmpnam函数由int变为void

[wdfk-prog]

_sys_tmpnam函数

/**
 * used by tmpnam() or tmpfile()
 */
int _sys_tmpnam(char *name, int fileno, unsigned maxlength)
{
    rt_snprintf(name, maxlength, "tem%03d", fileno);
    return 1;
}

MDK5.8 AC6声明函数

/*
 * Legacy variant of _sys_tmpnam2, which returns void and has no way
 * to report failure. If you implement this, the library will provide
 * a _sys_tmpnam2 wrapper that calls it.
 */
extern void _sys_tmpnam(char * /*name*/, int /*sig*/, unsigned /*maxlen*/);

是否需要更改？

需要的
可以通过例如#if __ARMCC_VERSION >= 6010050 的方法区分一下
