wfdcfg_keyval

Array(s) of this structure are used to allow for extensions

Synopsis:

#include <wfdqnx/wfdcfg.h>

struct wfdcfg_keyval {
    const char* key;
    long i;
    void* p;
} ;

Data:

const char* key: Identifier of extension.
long i: Data associated with extension.
void* p: Data associated with extension.

Library:

libwfdcfg

Description:

Extensions can exist on each of the following:

device: access these via wfdcfg_device_get_extension().
port: access these via wfdcfg_port_get_extension().
mode: access these via wfdcfg_mode_get_extension().
mode_list: access these via wfdcfg_mode_list_get_extension().

Several Wfdcfg library functions take this structure as an optional argument; certain drivers pass data to the Wfdcfg library using this interface.

The i and p members of this structure depend on the key (when part of an array, an element with key==NULL marks the end of that array). Unused i and/or p fields should be set to 0 or NULL.
