小妹--向大家请教多语言排序问题
HI:

在linux平台。我想对 多种语言进行排序。比如说对日语，汉字，韩语.....
请问1）该怎么做？
2) 是否有支持多语言比较的API.或者库函数。
谢谢了。 排序

STRCOLL
Section: POSIX Programmer's Manual (P)
Updated: 2003
--------------------------------------------------------------------------------

NAME
strcoll - string comparison using collating information
SYNOPSIS
#include <string.h>


int strcoll(const char *s1, const char *s2);


DESCRIPTION
The strcoll() function shall compare the string pointed to by s1 to the string pointed to by s2, both interpreted as appropriate to the LC_COLLATE category of the current locale.

The strcoll() function shall not change the setting of errno if successful.

Since no return value is reserved to indicate an error, an application wishing to check for error situations should set errno to 0, then call strcoll(), then check errno.

RETURN VALUE
Upon successful completion, strcoll() shall return an integer greater than, equal to, or less than 0, according to whether the string pointed to by s1 is greater than, equal to, or less than the string pointed to by s2 when both are interpreted as appropriate to the current locale. On error, strcoll() may set errno, but no return value is reserved to indicate an error.

ERRORS
The strcoll() function may fail if:

EINVAL
The s1 or s2 arguments contain characters outside the domain of the collating sequence.

The following sections are informative.

EXAMPLES

Comparing Nodes
The following example uses an application-defined function, node_compare(), to compare two nodes based on an alphabetical ordering of the string field.



#include <string.h>
...
struct node { /* These are stored in the table. */
char *string;
int length;
};
...
int node_compare(const void *node1, const void *node2)
{
return strcoll(((const struct node *)node1)->string,
((const struct node *)node2)->string);
}
...



APPLICATION USAGE
The strxfrm() and strcmp() functions should be used for sorting large lists.

RATIONALE
None.

FUTURE DIRECTIONS
None.
