/spawnpoint @s

Sets your spawn point to your current location.

/spawnpoint @a 0 64 0

Sets all players' spawn points to coordinates 0, 64, 0.

/spawnpoint @p ~ ~ ~ 90

Sets the nearest player's spawn point to their current location, facing east on respawn.

Setting a spawn point inside a solid block, the player may suffocate or be displaced on respawn.
Confusing /spawnpoint (per-player) with /setworldspawn (global default).

Each player has an individual spawn point. If the spawn point block becomes obstructed, the player respawns at the world spawn instead.
