.ig @(#)stat.2 2.1 7/1/84 @(#)Copyright (C) 1983 by National Semiconductor Corp. .. .TH STAT 2 .SH NAME stat, fstat \- get file status .SH SYNOPSIS .nf .B #include <sys/types.h> .B #include <sys/stat.h> .PP .B stat(name, buf) .B char *name; .B struct stat *buf; .PP .B fstat(fildes, buf) .B struct stat *buf; .fi .SH DESCRIPTION .I Stat obtains detailed information about a named file. .I Fstat obtains the same information about an open file known by the file descriptor from a successful .I open, creat, dup or .IR pipe (2) call. .PP .I Name points to a null-terminated string naming a file; .I buf is the address of a buffer into which information is placed concerning the file. It is unnecessary to have any permissions at all with respect to the file, but all directories leading to the file must be searchable. The layout of the structure pointed to by buf as defined in .I <stat.h> is given below. .I St_mode is encoded according to the `#define' statements. .PP .nf .ta 5m 10m 15m 20m 25m 30m 35m 40m 45m 50m 55m 60m .so ../include/sys/stat.h .fi .DT .PP The mode bits 0000070 and 0000007 encode group and others permissions (see .IR chmod (2)). The defined types, .I ino_t, off_t, time_t, name various width integer values; .I dev_t encodes major and minor device numbers; their exact definitions are in the include file <sys/types.h> (see .IR types (5)). .PP When .I fildes is associated with a pipe, .I fstat reports an ordinary file with an i-node number, restricted permissions, and a not necessarily meaningful length. .PP .I st_atime is the time the file was last read. For reasons of efficiency, it is not set when a directory is searched, although this would be more logical. .I st_mtime is the time the file was last written or created. It is not set by changes of owner, group, link count, or mode. .I st_ctime is set both by writing and changing the i-node. .SH "SEE ALSO" ls(1), filsys(5) .SH DIAGNOSTICS Zero is returned if a status is available; \-1 if the file cannot be found.
