Typedefs

typedef struct tapi_flow_s tapi_flow_t

General Flow structure List of endpoints and traffic entries

Global Functions

char* tapi_flow_preprocess_links(const char* param)

Preprocess parameter value and resolve all configurator links within.

Parameters:

param

Textual parameter value to preprocess

Returns:

Preprocessed value on success or NULL on any error

char* tapi_flow_preprocess_quotes(const char* param)

Preprocess parameter value and substitute quoted values. Quoted notation is used to increase readability Also dereference configurator links if quotting means configurator link reduction.

Parameters:

param

Textual parameter value to preprocess

Returns:

Preprocessed value on success or NULL on any error

char** tapi_flow_preprocess_args(int argc, char** argv)

Preprocess all test arguments

Parameters:

argc	Amount of arguments to preprocess
argv	Array of test arguments

Returns:

Array of preprocessed arguments on success or NULL on any error

te_errno tapi_flow_conf_get(int argc, char** argv, bool do_preprocess, tapi_flow_t* flow)

Get and process flow parametrisation from test arguments

Parameters:

argc	Amount of arguments to preprocess
argv	Array of test arguments
flow	Initialised flow structure (OUT)

Returns:

0, if success, or -1 otherwise

tapi_flow_ep* tapi_flow_find_ep(tapi_flow_t* flow, const char* name)

Find Endpoint by its name

Parameters:

flow	Flow structure to find endpoint in
name	Name of endpoint to find

Returns:

Endpoint structure, if success, or NULL otherwise

tapi_flow_traffic* tapi_flow_find_traffic(tapi_flow_t* flow, const char* name)

Find Traffic Entry by its name

Parameters:

flow	Flow structure to find traffic entry in
name	Name of traffic entry to find

Returns:

Endpoint structure, if success, or NULL otherwise

Macros

#define TEST_GET_FLOW_CONFIG(_flow, _do_preprocess)

Read configuration from test’s parameters

Parameters:

platfrom_config

Pointer to platform_config_s structure to receive configuration (OUT)
