Unicode相当于gcvt（）方法 [英] Unicode equivalent of gcvt() method

问题描述

大家好，



在我的项目中，gcvt（）用于将浮点值转换为char值，现在我们支持unicode，因此我想将浮动值转换为宽字符。



gcvt（FloatValue，5，CharBuffer）; //之前用的是



我没有看到任何unicode等效的gcvt（）方法，我怎么能用unodeode版本的sprintf（）来实现呢作为参数??



请记住，我需要将特定数量的浮点字符复制到TCHAR缓冲区。









问候，

Hello guys,

In my project gcvt() was used to convert a float value in to char value,now we are supporting unicode, hence I would like to convert float value in to wide characters.

gcvt(FloatValue, 5, CharBuffer); // was used earlier

I do not see any unicode equivalent of gcvt() method, how can I do it using unicode version of sprintf() that also takes count as argument??

Please remember, I need to copy particular number of float characters in to TCHAR buffer.




Regards,
joy

推荐答案

gcvt（）是一个旧的POSIX函数。它已从POSIX规范中删除，并且在Linux等实际POSIX系统上不再可用。从未指定过宽字符版本。建议将所有来电替换为 ecvt ， fcvt 和 gcvt 使用 sprintf 。



相当于 _stprintf 你的例子的函数调用是：

gcvt() is an old POSIX function. It has been removed from the POSIX specification and is no longer available on actual POSIX systems like Linux. A wide character version has never been specified. It is recommended to replace all calls to ecvt, fcvt, and gcvt by using sprintf.

The equivalent _stprintf function call for your example is:

_stprintf(CharBuffer, _T("%.5g"), FloatValue);

这是POSIX所以我认为它没有等价物。您需要使用这些功能 [ ^ ]。

That's POSIX so I don't think it has an equivalent. You need to use these functions[^].
