The _stat structure, defined in SYS\STAT.H, includes the following fields.
st_gid
Numeric identifier of group that owns file (UNIX-specific) This field will always be zero on NT systems. A redirected file is classified as an NT file.
st_atime
Time of last access of file.
st_ctime
Time of creation of file.
st_dev
Drive number of the disk containing the file (same as st_rdev).
st_ino
Number of the information node (the inode) for the file (UNIX-specific). On UNIX file systems, the inode describes the file date and time stamps, permissions, and content. When files are hard-linked to one another, they share the same inode. The inode, and therefore st_ino, has no meaning in the FAT, HPFS, or NTFS file systems.
st_mode
Bit mask for file-mode information. The _S_IFDIR bit is set if path specifies a directory; the _S_IFREG bit is set if path specifies an ordinary file or a device. User read/write bits are set according to the file’s permission mode; user execute bits are set according to the filename extension.
st_mtime
Time of last modification of file.
st_nlink
Always 1 on non-NTFS file systems.
st_rdev
Drive number of the disk containing the file (same as st_dev).
st_size
Size of the file in bytes; a 64-bit integer for _stati64 and _wstati64
st_uid
Numeric identifier of user who owns file (UNIX-specific). This field will always be zero on NT systems. A redirected file is classified as an NT file.
If path refers to a device, the size, time, _dev, and _rdev fields in the _stat structure are meaningless. Because STAT.H uses the _dev_t type that is defined in TYPES.H, you must include TYPES.H before STAT.H in your code.
Example
/* STAT.C: This program uses the _stat function to * report information about the file named STAT.C. */ #include <time.h> #include <sys/types.h> #include <sys/stat.h> #include <stdio.h> void main( void ) { struct _stat buf; int result; char buffer[] = "A line to output"; /* Get data associated with "stat.c": */ result = _stat( "stat.c", &buf ); /* Check if statistics are valid: */ if( result != 0 ) perror( "Problem getting information" ); else { /* Output some of the statistics: */ printf( "File size : %ld\n", buf.st_size ); printf( "Drive : %c:\n", buf.st_dev + 'A' ); printf( "Time modified : %s", ctime( &buf.st_atime ) ); } }
Output
File size : 745 Drive : C: Time modified : Tue May 03 00:00:00 1994
