.Dt SQLITE_ACCESS_EXISTS 3
.Os
.Sh NAME
.Nm SQLITE_ACCESS_EXISTS ,
.Nm SQLITE_ACCESS_READWRITE ,
.Nm SQLITE_ACCESS_READ
.Nd flags for the xAccess VFS method
.Sh SYNOPSIS
.In sqlite3.h
.Fd #define SQLITE_ACCESS_EXISTS
.Fd #define SQLITE_ACCESS_READWRITE
.Fd #define SQLITE_ACCESS_READ
.Sh DESCRIPTION
These integer constants can be used as the third parameter to the xAccess
method of an sqlite3_vfs object.
They determine what kind of permissions the xAccess method is looking
for.
With SQLITE_ACCESS_EXISTS, the xAccess method simply checks whether
the file exists.
With SQLITE_ACCESS_READWRITE, the xAccess method checks whether the
named directory is both readable and writable (in other words, if files
can be added, removed, and renamed within the directory).
The SQLITE_ACCESS_READWRITE constant is currently used only by the
temp_store_directory pragma, though this
could change in a future release of SQLite.
With SQLITE_ACCESS_READ, the xAccess method checks whether the file
is readable.
The SQLITE_ACCESS_READ constant is currently unused, though it might
be used in a future release of SQLite.
.Sh IMPLEMENTATION NOTES
These declarations were extracted from the
interface documentation at line 1505.
.Bd -literal
#define SQLITE_ACCESS_EXISTS 0
#define SQLITE_ACCESS_READWRITE 1 /* Used by PRAGMA temp_store_directory */
#define SQLITE_ACCESS_READ 2 /* Unused */
