Member Function Documentation

Close()

void CPosixFile::Close ( )

overridevirtual

Implements XFILE::IFile.

Delete()

bool CPosixFile::Delete ( const CURL & url )

overridevirtual

Reimplemented from XFILE::IFile.

Exists()

bool CPosixFile::Exists ( const CURL & url )

overridevirtual

Implements XFILE::IFile.

Flush()

void CPosixFile::Flush ( )

overridevirtual

Reimplemented from XFILE::IFile.

GetLength()

int64_t CPosixFile::GetLength ( )

overridevirtual

Implements XFILE::IFile.

GetPosition()

int64_t CPosixFile::GetPosition ( )

overridevirtual

Implements XFILE::IFile.

IoControl()

int CPosixFile::IoControl ( EIoControl request, void * param )

overridevirtual

Reimplemented from XFILE::IFile.

Open()

bool CPosixFile::Open ( const CURL & url )

overridevirtual

Implements XFILE::IFile.

OpenForWrite()

bool CPosixFile::OpenForWrite ( const CURL & url, bool bOverWrite = false )

overridevirtual

Reimplemented from XFILE::IFile.

Read()

ssize_t CPosixFile::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.

Rename()

bool CPosixFile::Rename ( const CURL & url, const CURL & urlnew )

overridevirtual

Reimplemented from XFILE::IFile.

Seek()

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

overridevirtual

Implements XFILE::IFile.

Stat() [1/2]

int CPosixFile::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.

Stat() [2/2]

int CPosixFile::Stat ( struct __stat64 * buffer )

overridevirtual

Fills struct __stat64 with information about currently open file 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

buffer

pointer to __stat64 buffer to receive information about file

Returns

zero of success, -1 otherwise.

Reimplemented from XFILE::IFile.

Truncate()

int CPosixFile::Truncate ( int64_t size )

overridevirtual

Reimplemented from XFILE::IFile.

Write()

ssize_t CPosixFile::Write ( const void * bufPtr, size_t bufSize )

overridevirtual

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

Parameters

bufPtr	pointer to buffer
bufSize	size of the buffer

Returns

number of successfully written bytes if any bytes were written, zero if no bytes were written and no detectable error occur, -1 in case of any explicit error

Reimplemented from XFILE::IFile.
