sam_data_store: Store user data
cs_error_t sam_data_store (const void *data, size_t size);
The sam_data_store function is used to store data, which survives between instances.
The data parameter is pointer to memory with data to store. Data are stored in newly allocated memory inside library, so caller can safely remove them after call of function.
You can use NULL as parameter to remove and free previously saved data. In this case size argument is ignored.
The size parameter is length of data.
This call return CS_OK value if successful, otherwise and error is returned.
- component was not initialized by calling sam_initialize(3) or it was finalized.
- internal malloc/realloc failed because data are too large
some internal error appeared (mostly because communication with parent process failed)
