Function RM_ReplyWithError

src/module.cpp:1547–1552

Reply with the error 'err'. * * Note that 'err' must contain all the error, including * the initial error code. The function only provides the initial "-", so * the usage is, for example: * * RedisModule_ReplyWithError(ctx,"ERR Wrong Type"); * * and not just: * * RedisModule_ReplyWithError(ctx,"Wrong Type"); * * The function always returns REDISMODULE_OK. */

 * The function always returns REDISMODULE_OK.
