函数原型：int string_unescape(char *src, char *dst, size_t size, unsigned int flags)

返回类型：int

参数：

类型参数名称
char *src
char *dst
size_tsize
unsigned intflags
270  out等于dst
272  当src且size先自减循环
273  如果src[0]恒等于'\\'且src[1]不等于'\0'且size大于1则
274  src自加
275  size自减
277  如果flags按位与UNESCAPE_SPACE且unescape_space( & src, & out)则继续下一循环
281  如果flags按位与UNESCAPE_OCTAL且unescape_octal( & src, & out)则继续下一循环
285  如果flags按位与UNESCAPE_HEX且unescape_hex( & src, & out)则继续下一循环
289  如果flags按位与UNESCAPE_SPECIAL且unescape_special( & src, & out)则继续下一循环
293  out自加等于'\\'
295  out自加等于src自加
297  out等于'\0'
299  返回:out减dst
