wfdcfg_keyval

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

Synopsis:

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.
