FD

File descriptor wrapper

This wrapper's main purpose is to protect the fd against leakage. It does not actually do anything.

struct FD {

this(string path, int flags, mode_t mode);

static FD adopt(int fd);

auto osCall(T args);

auto read(void[] buffer);

auto write(void[] buffer);

auto checkedCall(T args, string errorMessage);

void close();

int fileNo [@property getter];

bool isValid [@property getter];

}

Constructors

this this(int fd): Initialize from an OS file descriptor.
this this(string path, int flags, mode_t mode): Open a new file.

Destructor

~this ~this(): Undocumented in source.

Postblit

this(this) this(this): Undocumented in source.

Members

Functions

checkedCall auto checkedCall(T args, string errorMessage): Run an fd based function and throw if it fails
close void close(): Close the OS handle prematurely.
dup FD dup(): Duplicate an FD
osCall auto osCall(T args): Call an OS function that accepts an FD as the first argument.
read auto read(void[] buffer): @safe read
write auto write(void[] buffer): @safe write

Properties

fileNo int fileNo [@property getter]: Obtain the underlying OS handle
isValid bool isValid [@property getter]: Report whether the FD currently holds a valid fd

Static functions

adopt FD adopt(int fd): Wrapper for adopting an fd immediately after being returned from external function
