lstat64_time64()--Get File or Link Information (large file and time64_t enabled)
Syntax
#include <sys/stat.h> int lstat64_time64(const char *path, struct stat64_time64 *buf);Service Program Name: QP0LLIB1
Default Public Authority: *USE
Threadsafe: Conditional; see Usage Notes for lstat().
The lstat64_time64() function gets status information about a specified file and places it in the area of memory pointed to by buf. If the named file is a symbolic link, lstat64_time64() returns information about the symbolic link itself.
The information is returned in the stat64_time64 structure, referred to by buf. For details on the stat64_time64 structure, see stat64_time64()--Get File Information (large file and time64_t enabled).
If the named file is not a symbolic link, lstat64_time64() updates the time-related fields before putting information in the stat64_time64 structure.
For additional information about parameters, authorities required, and error conditions, see lstat()--Get File or Link Information.
See QlgLstat64_time64()--Get File or Link Information (large file and time64_t enabled) for a description and an example of supplying the path in any CCSID.
Usage Notes
- When you develop in C-based languages, the prototypes for the 64-bit APIs
are normally hidden. To use the lstat64_time64() API and the
struct stat64_time64 data type, you must compile the source with the
_LARGE_FILE_API defined.
- While the st_atime, st_mtime, and st_ctime fields are time64_t fields, the API will
not return time values beyond what can be contained in a time_t field.
- All of the usage notes for lstat() apply to lstat64_time64(). See Usage Notes in the lstat() API.
Example
The following example provides status information for a file.

#define _LARGE_FILE_API #include <sys/types.h> #include <sys/stat.h> #include <stdio.h> #include <fcntl.h> #include <unistd.h> #include <time.h> #include <stdio.h> main() { char fn[]="temp.file", ln[]="temp.link"; struct stat64_time64 info; int file_descriptor; if ((file_descriptor = creat64(fn, S_IWUSR)) < 0) perror("creat64() error"); else { close(file_descriptor); if (link(fn, ln) != 0) perror("link() error"); else { if (lstat64_time64(ln, &info) != 0) perror("lstat64_time64() error"); else { puts("lstat64_time64() returned:"); printf(" inode: %d\n", (int) info.st_ino); printf(" dev id: %d\n", (int) info.st_dev); printf(" mode: %08x\n", info.st_mode); printf(" links: %d\n", info.st_nlink); printf(" uid: %d\n", (int) info.st_uid); printf(" gid: %d\n", (int) info.st_gid); printf(" size: %lld\n", (long long) info.st_size); } unlink(ln); } unlink(fn); } }
Output:
lstat64_time64() returned: inode: 3022 dev id: 1 mode: 00008080 links: 2 uid: 137 gid: 500 size: 18
