Detailed Description

Non-refcounted RAII wrapper for FILE*.

Will automatically close the file when it goes out of scope if not null. If you're returning the file pointer, return file.release(). If you need to close the file early, use file.fclose() instead of fclose(file).

Here is the caller graph for this function:

FILE* CAutoFile::Get ( ) const

inline

Get wrapped FILE* without transfer of ownership.

Note

Ownership of the FILE* will remain with this class. Use this only if the scope of the CAutoFile outlives use of the passed pointer.

Here is the caller graph for this function:

int CAutoFile::GetType ( ) const

int CAutoFile::GetVersion ( ) const

Definition at line 506 of file streams.h.

void CAutoFile::ignore ( size_t  nSize )

inline

Definition at line 516 of file streams.h.

bool CAutoFile::IsNull ( ) const

inline

Return true if the wrapped FILE* is nullptr, false otherwise.

Definition at line 500 of file streams.h.

Here is the caller graph for this function:

template<typename T >

CAutoFile& CAutoFile::operator<< ( const T &  obj )

inline

Definition at line 538 of file streams.h.

Here is the call graph for this function:

CAutoFile& CAutoFile::operator= ( const CAutoFile &  )

private

template<typename T >

CAutoFile& CAutoFile::operator>> ( T &  obj )

inline

Definition at line 548 of file streams.h.

Here is the call graph for this function:

void CAutoFile::read ( char *  pch, size_t  nSize  )

inline

Definition at line 508 of file streams.h.

FILE* CAutoFile::release ( )

inline

Get wrapped FILE* with transfer of ownership.

Note

This will invalidate the CAutoFile object, and makes it the responsibility of the caller of this function to clean up the returned FILE*.

Definition at line 490 of file streams.h.

void CAutoFile::write ( const char *  pch, size_t  nSize  )

inline

Definition at line 529 of file streams.h.
