app/redis-6.2.6/src/db.c:1649–1657

Return all the arguments that are keys in the command passed via argc / argv. * * The command returns the positions of all the key arguments inside the array, * so the actual return value is a heap allocated array of integers. The * length of the array is returned by reference into *numkeys. * * 'cmd' must be point to the corresponding entry into the redisCommand * table, according to the c

 * This function uses the command table if a command-specific helper function
 * is not required, otherwise it calls the command-specific function. */
