VFSFileInput

Provides basic file input functionality - seeking and reading.

VFSFileInput uses reference counting so that the file is closed when the last instance of VFSFileInput provided by the file is destroyed.

struct VFSFileInput {

void[] read(void[] target);

void seek(long offset, Seek origin);

void opAssign(VFSFileInput rhs);

this(VFSFile file);

}

Constructors

Functions

opAssign void opAssign(VFSFileInput rhs): Undocumented in source. Be warned that the author may not have intended to support it.
read void[] read(void[] target): Read at most target.length bytes starting at current file position to target.
seek void seek(long offset, Seek origin): Set file position to offset bytes from specified origin.

Examples

VFSFile file; //initialized somewhere before

auto input = file.input;
with(input)
{
    auto buffer = new ubyte[32];

    //Read the first 32 bytes from the file:
    read(buffer);

    //Read the next 32 bytes:
    read(buffer);

    //Read the last 32 bytes in the file:
    seek(-32, file);
    read(buffer);
}
