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).

Constructor & Destructor Documentation

◆ CAutoFile() [1/2]

CAutoFile::CAutoFile ( FILE *  filenew,
int  nTypeIn,
int  nVersionIn 
)
inline

Definition at line 589 of file streams.h.

◆ ~CAutoFile()

CAutoFile::~CAutoFile ( )
inline

Definition at line 594 of file streams.h.

Here is the call graph for this function:

◆ CAutoFile() [2/2]

CAutoFile::CAutoFile ( const CAutoFile )
delete

Member Function Documentation

◆ fclose()

void CAutoFile::fclose ( )
inline

Definition at line 600 of file streams.h.

Here is the caller graph for this function:

◆ Get()

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.

Definition at line 624 of file streams.h.

Here is the caller graph for this function:

◆ GetType()

int CAutoFile::GetType ( ) const
inline

Definition at line 632 of file streams.h.

◆ GetVersion()

int CAutoFile::GetVersion ( ) const
inline

Definition at line 633 of file streams.h.

Here is the caller graph for this function:

◆ ignore()

void CAutoFile::ignore ( size_t  nSize)
inline

Definition at line 647 of file streams.h.

◆ IsNull()

bool CAutoFile::IsNull ( ) const
inline

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

Definition at line 627 of file streams.h.

Here is the caller graph for this function:

◆ operator<<()

template<typename T >
CAutoFile& CAutoFile::operator<< ( const T &  obj)
inline

Definition at line 674 of file streams.h.

Here is the call graph for this function:

◆ operator=()

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

◆ operator>>()

template<typename T >
CAutoFile& CAutoFile::operator>> ( T &&  obj)
inline

Definition at line 684 of file streams.h.

Here is the call graph for this function:

◆ read()

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

Definition at line 635 of file streams.h.

◆ release()

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 613 of file streams.h.

◆ write()

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

Definition at line 664 of file streams.h.
