Detailed Description

I/O example binding.

All functions except the I/O binding entry point (elektraIoDocNew()) would normally be static but for documentation purposes they are not.

Typedef Documentation

◆ DocBindingData

[kdbio operation data]

[kdbio binding data] Container for additional information for an I/O binding.

◆ DocOperationData

[kdbio operation data]

Container for additional information for I/O binding operations.

It is helpful to create a data structure for your binding to store additional data

Enumeration Type Documentation

◆ SomeIoLibFlags

Example I/O mangement library bitmask flags.

Enumerator
SOME_IOLIB_READABLE 

indicates that the file descriptor is readable

SOME_IOLIB_WRITABLE 

indicates that the file descriptor is readable

Function Documentation

◆ elektraIoDocNew()

ElektraIoInterface* elektraIoDocNew ( char *  foo)

Create and initialize a new doc I/O binding.

Parameters
fooSome data from I/O management library (e.g. a handle)
Returns
Populated I/O interface

◆ ioDocBindingFdCallback()

void ioDocBindingFdCallback ( SomeIoLibHandle handle,
int  bitmask
