Function RM_ZsetFirstInScoreRange

app/redis-6.2.6/src/module.c:2818–2820

Setup a sorted set iterator seeking the first element in the specified * range. Returns REDISMODULE_OK if the iterator was correctly initialized * otherwise REDISMODULE_ERR is returned in the following conditions: * * 1. The value stored at key is not a sorted set or the key is empty. * * The range is specified according to the two double values 'min' and 'max'. * Both can be infinite using

 * where the min and max value are exclusive (not included) instead of
 * inclusive. */

/* Exactly like RedisModule_ZsetFirstInScoreRange() but the last element of
 * the range is selected for the start of the iteration instead. */
