NAME

SYNOPSIS

cs_error_t sam_data_store (const void *data, size_t size);

DESCRIPTION

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.

Use sam_data_getsize(3) to find out length of stored data and sam_data_restore(3) to restore stored data.
