man sscanf：%d 在 C 中已弃用？

Question

我刚刚阅读了

sscanf

手册页，发现了以下内容：

The following conversion specifiers are available:

       (...)

       d      Deprecated.   Matches  an optionally signed decimal integer; the
              next pointer must be a pointer to int.

       i      Deprecated.  Matches an  optionally  signed  integer;  the  next
              pointer  must  be a pointer to int.  The integer is read in base
              16 if it begins with 0x or 0X, in base 8 if it  begins  with  0,
              and  in  base  10 otherwise.  Only characters that correspond to
              the base are used.

       o      Deprecated.  Matches an unsigned octal integer; the next pointer
              must be a pointer to unsigned int.

       (...)

为什么

%d

被弃用了？似乎所有

int

说明符均已弃用。

这是什么意思以及有什么可以替代它们？

正如评论中所指出的（感谢@JeffHolt，@Eugene-sh，@DanielWalker，@Barmar，@DanielWalker），答案确实在Bugs部分：

BUGS
   Numeric conversion specifiers
       Use of the numeric conversion specifiers produces Undefined
       Behavior for invalid input.  See C11 7.21.6.2/10 
       ⟨https://port70.net/%7Ensz/c/c11/n1570.html#7.21.6.2p10⟩.  This is
       a bug in the ISO C standard, and not an inherent design issue
       with the API.  However, current implementations are not safe from
       that bug, so it is not recommended to use them.  Instead,
       programs should use functions such as strtol(3) to parse numeric
       input.  This manual page deprecates use of the numeric conversion
       specifiers until they are fixed by ISO C.

我确实同意“弃用”在这里的意思是“明确反对”（来自@Barmar的评论）。
