Method: FFI::Libfuse::FuseOperations#read_buf

Defined in:

lib/ffi/libfuse/fuse_operations.rb

#read_buf(path, bufp, size, offset, fuse_file_info) ⇒ Object

This method is abstract.

Similar to the #read method, but data is stored and returned in a generic buffer.

No actual copying of data has to take place, the source file descriptor may simply be stored in the buffer for later data transfer.

Parameters:

• path (String)
• bufp (FFI::Pointer<FuseBufVec>) —

  The buffer must be allocated dynamically (FFI::Libfuse::FuseBufVec.init) and stored at the location pointed to by bufp (see FFI::Libfuse::FuseBufVec#store_to(bufp)).

• size (Integer)
• offset (Integer)
• fuse_file_info (FuseFileInfo)

Returns:

• 0 success or -ve errno
