QlgLstat64()--Get File or Link Information (large file enabled and using NLS-enabled path name)

 #include <sys/stat.h>

 int QlgLstat64(Qlg_Path_Name_T *path, struct stat64 *buf);  

The QlgLstat64() function, like the lstat64() function, gets status information about a specified file and places it in the area of memory pointed to by buf. The difference is that the QlgLstat64() function takes a pointer to a Qlg_Path_Name_T structure, while lstat64() takes a pointer to a character string.

Limited information about the path parameter is provided here. For more information about the path parameter and for a discussion of other parameters, authorities required, return values, and related information, see lstat64()--Get File or Link Information (Large File Enabled) or lstat()--Get File or Link Information.

Parameters

path

(Input) A pointer to a Qlg_Path_Name_T structure that contains a path name or a pointer to a path name of the file. For more information about the Qlg_Path_Name_T structure, see Path name format.
