QlgUtime_time64()--Set File Access and Modification Times (time64_t enabled and using NLS-enabled path name)
Syntax
#include <utime.h> int QlgUtime_time64(Qlg_Path_Name_T *path, const struct utimbuf_time64 *times);Service Program Name: QP0LLIB1
Default Public Authority: *USE
Threadsafe: Conditional; see Usage Notes for utime().
The QlgUtime_time64() function, like the utime_time64() function, sets the access and modification times of path to the values in the utimbuf_time64 structure. The difference is that the QlgUtime_time64() function takes a pointer to a Qlg_Path_Name_T structure, while utime_time64() 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 utime_time64()--Set File Access and Modification Times (time64_t enabled).
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 which the times should be changed. For more information about the Qlg_Path_Name_T structure, see Path name format.

Output:
