getgrgid_r_ts64()--Get Group Information Using Group ID

 #include <sys/types.h>
 #include <grp.h>

 int getgrgid_r_ts64(
        gid_t gid,
        struct group * __ptr64 grp,
        char * __prt64 buffer,
        size_t bufsize,
        struct group * __ptr64 * __ptr64 result);    

The getgrgid_r_ts64() function updates the group structure pointed to by grp and stores a pointer to that structure in the location pointed to by result. The structure contains an entry from the user database with a matching GID. getgrgid_r_ts64() differs from getgrgid_r() in that it accepts 8-byte teraspace pointers.
