ni_get_valid_routes(9)

💅 NAME 💅

Hiii bestie! Welcome to ni_get_valid_routes(9) from the Kernel API Manual. This one’s short and sweet: it implements INSN_DEVICE_CONFIG_GET_ROUTES. That’s the whole vibe. ✨

🎀 SYNOPSIS 🎀

unsigned int ni_get_valid_routes (const struct ni_route_tables *tables ,
unsigned int n_pairs , unsigned int *pair_data );

🌸 ARGUMENTS 🌸

• tables — pointer to the relevant set of routing tables. That’s the routing-table home base.
• n_pairs — Number of pairs for which memory is allocated by the user. If the user specifies '0', only the number of available pairs is returned. So '0' is the “just tell me the count” mode, iykyk.
• pair_data — Pointer to memory allocated to return pairs back to user. Each even, odd indexed member of this array will hold source, destination of a route pair respectively. Even index = source, odd index = destination, and yes that is the arrangement.

🦋 RETURN 🦋

Here’s the return tea, bestie: the number of valid routes if n_pairs == 0; otherwise, the number of valid routes copied. That’s it — no extra plot twists. 💖
