Member Function Documentation

GetFP()

FILE * engine::FileMemoryBufferStreamFromFile::GetFP ( )

inlinevirtual

Direct access to the file. Do not close by yourself.

Implements engine::FileStreamI.

Read()

size_t engine::FileMemoryBufferStreamFromFile::Read ( void *  ptr, size_t  size, size_t  maxnum  )

virtual

Read up to maxnum objects each of size size from the data stream to the area pointed at by ptr.

Returns

the number of objects read, or 0 at error or end of file.

Implements engine::FileStreamI.

ReadBufferString()

std::string engine::FileMemoryBufferStreamFromFile::ReadBufferString ( )

virtual

Helper to read the whole file as string

Implements engine::FileStreamI.

Seek()

int64_t engine::FileMemoryBufferStreamFromFile::Seek ( int64_t  offset, int  whence  )

virtual

Seek to offset relative to whence, one of stdio's whence values: RW_SEEK_SET, RW_SEEK_CUR, RW_SEEK_END

Returns

the final offset in the data stream, or -1 on error.

Implements engine::FileStreamI.
