.SH NAME
strxfrm \- 转换字符串

.SH "总览 (SYNOPSIS)"
.nf
.B #include <string.h>
.sp
.BI "size_t strxfrm(char *" dest ", const char *" src ", size_t " n );
.fi

.SH "描述 (DESCRIPTION)"
\fBstrxfrm()\fP 函数 把 字符串 \fIsrc\fP 转换 成 另外 一种 形式. 用
\fBstrcmp()\fP 来比较 两个 转换后的 字符串 与 用 \fBstrcoll()\fP 来比较 它们
转换前的 字符串 的 返回值 是 一样的. 转换后的 字符串的 前 \fIn\fP 个 字符
会存放于 \fIdest\fP 中. 它是 根据 程序 当前的 区域选项 中的
\fILC_COLLATE\fP 来 转换的. (见 \fBsetlocale\fP(3)).

.SH "返回值 (RETURN VALUE)"
\fBstrxfrm()\fP 函数 返回 除去 结尾的 `\\0' 字符, 用来 存储 转换后的 字符串
所 需要的 字节数. 如果 返回值 大于 或 等于 \fIn\fP, \fIdest\fP 中的 内容
就是 不确定的.

.SH "遵循 (CONFORMING TO)"
SVID 3, BSD 4.3, ISO 9899

.SH "注意 (NOTES)"
如果 区域选项 是 \fI"POSIX"\fP 或者 \fI"C"\fP, 那么 \fBstrxfrm()\fP 同
用 \fBstrncpy()\fP 来 拷贝 字符串 是等价的.
