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).

fclose()

Here is the caller graph for this function:

Get()

FILE* AutoFile::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 AutoFile outlives use of the passed pointer.

Definition at line 567 of file streams.h.

Here is the caller graph for this function:

ignore()

void AutoFile::ignore ( size_t  nSize )

inline

Definition at line 587 of file streams.h.

IsNull()

bool AutoFile::IsNull ( ) const

inline

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

Here is the caller graph for this function:

operator<<()

Here is the call graph for this function:

read()

void AutoFile::read ( Span< std::byte >  dst )

inline

Definition at line 575 of file streams.h.

Here is the call graph for this function:

release()

FILE* AutoFile::release ( )

inline

Get wrapped FILE* with transfer of ownership.

Note

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

write()

void AutoFile::write ( Span< const std::byte >  src )

inline
