stat() and fstatat() retrieve information about the file pointed to by pathname; the differences for fstatat() are described below. lstat() is identical to stat(), except that if pathname is a symbolic link, then it returns information about the link itself, not the file that the link refers to.

Mar 13, 2018 · stat() function is used to list properties of a file identified by path. It reads all file properties and dumps to buf structure. The function is defined in sys/stat.h header file. Here *path is a pointer to constant character pointing to file path. *buf is a …

The stat () function shall obtain information about the named file and write it to the area pointed to by the buf argument. The path argument points to a pathname naming a file. Read, write, or execute permission of the named file is not required.

Since Linux 2.5.48, the stat structure supports nanosecond resolution for the three file timestamp fields. The nanosecond components of each timestamp are available via names of the form st_atim.tv_nsec, if suitable test macros are defined.

These functions return information about a file. No permissions are required on the file itself, but-in the case of stat() and lstat() - execute (search) permission is required on all of the directories in path that lead to the file. stat() stats the file pointed to by path and fills in buf.

Difference: Whenever the file name is a symbolic link, stat() returns the attributes or inode information about the target file associated with the link. Whereas, lstat() return the attributes of only the link.

Jun 8, 2018 · There are various power modes of the CPU which are determined on the basis of their current usage and are collectively called “C-states” or “C-modes.” The lower-power mode was first introduced with the 486DX4 processor.
