Constructor & Destructor Documentation

CImageFile()

CImageFile::CImageFile ( )

default

~CImageFile()

CImageFile::~CImageFile ( void )

override

Member Function Documentation

Close()

void CImageFile::Close ( )

overridevirtual

Implements XFILE::IFile.

Exists()

bool CImageFile::Exists ( const CURL & url )

overridevirtual

Implements XFILE::IFile.

GetLength()

int64_t CImageFile::GetLength ( )

overridevirtual

Implements XFILE::IFile.

GetPosition()

int64_t CImageFile::GetPosition ( )

overridevirtual

Implements XFILE::IFile.

Open()

bool CImageFile::Open ( const CURL & url )

overridevirtual

Implements XFILE::IFile.

Read()

ssize_t CImageFile::Read ( void * bufPtr, size_t bufSize )

overridevirtual

Attempt to read bufSize bytes from currently opened file into buffer bufPtr.

Parameters

bufPtr	pointer to buffer
bufSize	size of the buffer

Returns

number of successfully read bytes if any bytes were read and stored in buffer, zero if no bytes are available to read (end of file was reached) or undetectable error occur, -1 in case of any explicit error

Implements XFILE::IFile.

Seek()

int64_t CImageFile::Seek ( int64_t iFilePosition, int iWhence = SEEK_SET )

overridevirtual

Implements XFILE::IFile.

Stat()

int CImageFile::Stat ( const CURL & url, struct __stat64 * buffer )

overridevirtual

Fills struct __stat64 with information about file specified by url. For st_mode function will set correctly _S_IFDIR (directory) flag and may set _S_IREAD (read permission), _S_IWRITE (write permission) flags if such information is available. Function may set st_size (file size), st_atime, st_mtime, st_ctime (access, modification, creation times). Any other flags and members of __stat64 that didn't updated with actual file information will be set to zero (st_nlink can be set ether to 1 or zero).

Parameters

url	specifies requested file
buffer	pointer to __stat64 buffer to receive information about file

Returns

zero of success, -1 otherwise.

Implements XFILE::IFile.
