Here is the caller graph for this function:

xt_config_delete()

void xt_config_delete

(

Xt_config

config

)

destructor of configuration objects

Parameters

[in,out]

config

configuration object to destroy

Definition at line 76 of file xt_config.c.

xt_config_get_exchange_method()

int xt_config_get_exchange_method

(

Xt_config

config

)

get exchanger used when the config object is passed to constructors

Parameters

[in]

config

configuration object to modify

Returns

an entry from Xt_exchangers representing the method of data transfer used

Definition at line 111 of file xt_config.c.

xt_config_new()

Xt_config xt_config_new

(

void

)

constructor for configuration object

Returns

returns a configuration object where every setting is set to the corresponding default.

Definition at line 69 of file xt_config.c.

xt_config_set_exchange_method()

void xt_config_set_exchange_method	(	Xt_config	config,
		int	method
	)

set exchanger to use when the config object is passed to constructors

Parameters

[in,out]	config	configuration object to modify
	method	an entry from enum Xt_exchangers to signify the desired exchanger for data transfers

Definition at line 125 of file xt_config.c.

Here is the caller graph for this function:

xt_exchanger_id_by_name()

int xt_exchanger_id_by_name

(

const char *

name

)

map exchanger name string to method id from Xt_exchangers

Parameters

[in]

name

string that is supposed to match the part of the corresponding enum after xt_exchanger_

Returns

for the string "irecv_send", the value of xt_exchanger_irecv_send will be returned, for strings matching no known exchanger, -1 will be returned
