_locale_t是什么类型，有什么用

相关源代码如下：

typedef struct threadlocaleinfostruct {
        int refcount;
        unsigned int lc_codepage;
        unsigned int lc_collate_cp;
        unsigned long lc_handle[6]; /* LCID */
        LC_ID lc_id[6];
        struct {
            char *locale;
            wchar_t *wlocale;
            int *refcount;
            int *wrefcount;
        } lc_category[6];
        int lc_clike;
        int mb_cur_max;
        int * lconv_intl_refcount;
        int * lconv_num_refcount;
        int * lconv_mon_refcount;
        struct lconv * lconv;
        int * ctype1_refcount;
        unsigned short * ctype1;
        const unsigned short * pctype;
        const unsigned char * pclmap;
        const unsigned char * pcumap;
        struct __lc_time_data * lc_time_curr;
} threadlocinfo;

struct threadlocaleinfostruct;
struct threadmbcinfostruct;
typedef struct threadlocaleinfostruct * pthreadlocinfo;
typedef struct threadmbcinfostruct * pthreadmbcinfo;

typedef struct localeinfo_struct
{
    pthreadlocinfo locinfo;
