|map||The id of the data structure to use|
|filename||The name of the file to save the map to|
This function will save the contents of the given ds_map to a file. The file itself can have almost any extension (for example, *.dat, *.json, *.bin, etc...) and will be encrypted and stored to a safe location on the target platform. In this way you can store sensitive information, like in-app purchase details or passwords, locally in a secure way. You can then re-load the ds_map using the function ds_map_secure_load(). Note that if the DS map being saved contains an array, this array will be converted into a DS list instead when saved.
The above code will save the ds_map indexed in the variable "p_data" to the given file for later retrieval.
