-.TH Tcl_Access 3 8.1 Tcl "Tcl Library Procedures"
-.so man.macros
-.BS
-.SH NAME
-Tcl_Access, Tcl_Stat \- check file permissions and other attributes
-.SH SYNOPSIS
-.nf
-\fB#include <tcl.h>\fR
-.sp
-int
-\fBTcl_Access\fR(\fIpath\fR, \fImode\fR)
-.sp
-int
-\fBTcl_Stat\fR(\fIpath\fR, \fIstatPtr\fR)
-.SH ARGUMENTS
-.AS "struct stat" *statPtr out
-.AP char *path in
-Native name of the file to check the attributes of.
-.AP int mode in
-Mask consisting of one or more of \fBR_OK\fR, \fBW_OK\fR, \fBX_OK\fR and
-\fBF_OK\fR. \fBR_OK\fR, \fBW_OK\fR and \fBX_OK\fR request checking whether the
-file exists and has read, write and execute permissions, respectively.
-\fBF_OK\fR just requests a check for the existence of the file.
-.AP "struct stat" *statPtr out
-The structure that contains the result.
-.BE
-.SH DESCRIPTION
-.PP
-As of Tcl 8.4, the object-based APIs \fBTcl_FSAccess\fR and \fBTcl_FSStat\fR
-should be used in preference to \fBTcl_Access\fR and \fBTcl_Stat\fR, wherever
-possible. Those functions also support Tcl's virtual filesystem layer, which
-these do not.
-.SS "OBSOLETE FUNCTIONS"
-.PP
-There are two reasons for calling \fBTcl_Access\fR and \fBTcl_Stat\fR rather
-than calling system level functions \fBaccess\fR and \fBstat\fR directly.
-First, the Windows implementation of both functions fixes some bugs in the
-system level calls. Second, both \fBTcl_Access\fR and \fBTcl_Stat\fR (as well
-as \fBTcl_OpenFileChannelProc\fR) hook into a linked list of functions. This
-allows the possibility to reroute file access to alternative media or access
-methods.
-.PP
-\fBTcl_Access\fR checks whether the process would be allowed to read, write or
-test for existence of the file (or other file system object) whose name is
-\fIpath\fR. If \fIpath\fR is a symbolic link on Unix, then permissions of the
-file referred by this symbolic link are tested.
-.PP
-On success (all requested permissions granted), zero is returned. On error (at
-least one bit in mode asked for a permission that is denied, or some other
-error occurred), -1 is returned.
-.PP
-\fBTcl_Stat\fR fills the stat structure \fIstatPtr\fR with information about
-the specified file. You do not need any access rights to the file to get this
-information but you need search rights to all directories named in the path
-leading to the file. The stat structure includes info regarding device, inode
-(always 0 on Windows), privilege mode, nlink (always 1 on Windows), user id
-(always 0 on Windows), group id (always 0 on Windows), rdev (same as device on
-Windows), size, last access time, last modification time, and creation time.
-.PP
-If \fIpath\fR exists, \fBTcl_Stat\fR returns 0 and the stat structure is
-filled with data. Otherwise, -1 is returned, and no stat info is given.
-.SH KEYWORDS
-stat, access
