Member Function Documentation

virtual bool MountFile::isBytewise ( ) const
inlineprivatevirtual

File subclasses can define this and return true if they require read() calls to perform actual data reads, and false if readBlock() is otherwise sufficient.

Reimplemented from File.

Definition at line 111 of file ProcFs.h.

uint64_t MountFile::readBytewise ( uint64_t  location,
uint64_t  size,
uintptr_t  buffer,
bool  bCanBlock = true 
)
virtual

Reads bytes from the file, if isBytewise() == true.

Reimplemented from File.

Definition at line 230 of file ProcFs.cc.

uint64_t MountFile::writeBytewise ( uint64_t  location,
uint64_t  size,
uintptr_t  buffer,
bool  bCanBlock = true 
)
virtual

Writes bytes to the file, if isBytewise() == true.

Reimplemented from File.
