Function Documentation

__docker_info_init()

static int __docker_info_init ( struct json_object *  setting, int  index, struct docker_info *  info  )

static

Set the configuration of each process's behavior.

Parameters

[in]	setting	JSON object pointer which has the setting value.
[in]	index	task_option array's index.
[out]	info	The target structure of the member will be set by the JSON object.

Returns

0 for success to init, error number for fail to init

< Variable for hsearch.

Here is the call graph for this function:

docker_info_init()

struct docker_info* docker_info_init	(	struct json_object *	setting,
		int	index
	)

Generate and construct the per processes info object and return it.

Parameters

[in]	setting	JSON object pointer which has the setting value.
[in]	index	task_option array's index.

Returns

0 for success to init, error number for fail to init

Here is the call graph for this function:

docker_info_int_value_set()

static int docker_info_int_value_set ( struct json_object *  setting, const char *  key, unsigned int *  member, int  is_print  )

static

Read the JSON string and convert the value to integer form and set that value to info->(member)

Parameters

[in]	setting	The traverse start location of JSON object.
[in]	key	JSON object's key which points to the value I want to find.
[out]	member	info structure member address.
[in]	is_print	The flag that determines to print the error.

Returns

0 for success to input, -EINVAL for fail to input.

Warning

member must be an integer type.

docker_info_str_value_set()

static int docker_info_str_value_set ( struct json_object *  setting, const char *  key, char *  member, size_t  size, int  is_print  )

static

Read the JSON string and convert the value to string form and set that value to info->(member)

Parameters

[in]	setting	The traverse start location of JSON object.
[in]	key	JSON object's key which points to the value I want to find.
[out]	member	info structure member address.
[in]	size	This value must under member memory size
[in]	is_print	The flag that determines to print the error.

Returns

0 for success to input, -EINVAL for fail to input.

Warning

member must be an string type.

Here is the call graph for this function:

docker_is_synth_type()

int docker_is_synth_type

(

const char *

trace_data_path

)

Check the trace_data_path value form is synthetic from.

Parameters

[in]

trace_data_path

The value which I want to know either synthetic or not.

Returns

DOCKER_SYNTH for trace_data_path is synthetic, DOCKER_NOT_SYNTH for trace_data_path isn't synthetic

Variable Documentation

global_synth_type

const char* global_synth_type[]

static

Initial value:

= { "rand_read",  "rand_write",
                                           "rand_mixed", "seq_read",
                                           "seq_write",  "seq_mixed",
                                           NULL }

Definition of a well-known synthetic form. This value depends on the trace-replay specification.
