Functions

• int add_domain_data (struct carrier_data_t *carrier_data, struct domain_data_t *domain_data, int index)

  Adds a domain_data struct to the given carrier data structure at the given index.
  

• int compare_carrier_data (const void *v1, const void *v2)

  Compares the IDs of two carrier data structures.
  

• struct carrier_data_t * create_carrier_data (int carrier_id, str *carrier_name, int domains)

  Create a new carrier_data struct in shared memory and set it up.
  

• void destroy_carrier_data (struct carrier_data_t *carrier_data)

  Destroys the given carrier and frees the used memory.
  

• struct domain_data_t * get_domain_data (struct carrier_data_t *carrier_data, int domain_id)

  Returns the domain data for the given id by doing a binary search.

Function Documentation

int add_domain_data	(	struct carrier_data_t *	carrier_data,
		struct domain_data_t *	domain_data,
		int	index
	)

Other etries are moved one position up to make space for the new one.

Parameters:

	carrier_data	the carrier data struct where domain_data should be inserted
	domain_data	the domain data struct to be inserted
	index	the index where to insert the domain_data structure in the domain array

Returns:

0 on success, -1 on failure

int compare_carrier_data	(	const void *	v1,
		const void *	v2
	)

A NULL pointer is always greater than any ID.

Returns:

-1 if v1 < v2, 0 if v1 == v2, 1 if v1 > v2

Here is the caller graph for this function:

struct carrier_data_t* create_carrier_data	(	int	carrier_id,
		str *	carrier_name,
		int	domains
	)			[read]

Parameters:

	carrier_id	id of carrier
	carrier_name	pointer to the name of the carrier
	domains	number of domains for that carrier

Returns:

a pointer to the newly allocated carrier data or NULL on error, in which case it LOGs an error message.

struct domain_data_t* get_domain_data	(	struct carrier_data_t *	carrier_data,
		int	domain_id
	)			[read]

Note:

The domain array must be sorted!

Parameters:

	carrier_data	carrier data to be searched
	domain_id	the id of desired domain

Returns:

a pointer to the desired domain data, NULL if not found.
