Condition:

This type is used on Windows platforms.

Constructor & Destructor Documentation

RWFileStat::RWFileStat ( const char *  s, bool  follow_links = true  )

explicit

Constructs the object by using a stat function on the filename given in s. The call succeeds or throws an exception of type (or derived of) RWInternalErr . The error can be inspected by looking at errno. If the filename indicates a symbolic link, it uses a stat function on the target of the symbolic link rather than the symbolic link itself when the parameter follow_links is true (default). Otherwise, it uses a stat function on the symbolic link.

Member Function Documentation

time_t RWFileStat::atime

(

)

const

Returns the time of the last access.

time_t RWFileStat::ctime

(

)

const

Returns the time of the last status change.

device_type RWFileStat::dev

(

)

const

Returns the device number for the file.

inode_type RWFileStat::inode

(

)

const

Returns the inode number for the file.

bool RWFileStat::isBlock

(

)

const

Returns true if the file is a block device.

bool RWFileStat::isCharacter

(

)

const

Returns true if the file is a character device.

bool RWFileStat::isDirectory

(

)

const

Returns true if the file is a directory.

bool RWFileStat::isFifo

(

)

const

Returns true if the file is a FIFO named pipe.

bool RWFileStat::isFile

(

)

const

Returns true if the file is a regular file.

bool RWFileStat::isSymlink

(

)

const

Returns true if the file is a symlink. This member function always returns false for objects of type RWFileStat.

mode_type RWFileStat::mode

(

)

const

Returns an integer which is a bit mask value indicating the type of the file and the permissions for it.

time_t RWFileStat::mtime

(

)

const

Returns the time of the last modification.

nlink_type RWFileStat::nlink

(

)

const

Returns the number or hard links for the file.

offset_type RWFileStat::size

(

)

const

Returns the size of the file.

const stat_type* RWFileStat::stat

(

)

const

Returns a pointer to the underlying type. The type is a struct stat but it may change in the future. Using the returned type directly is not supported.
