关于调用api的问题

[ttlrwdl]

Public Declare Sub lmsg Lib "X1.dll" (ByVal sMsg As String)
我的问题 这里lmsg是什么啊 是dll里面的函数还是什么啊

Sub ExeSetTimer(ByVal nVer As Long, ByVal nTimerID As Long, ByVal Interval As Long, ByVal parm As String)


lmsg "ExeSetTimer:: Timer: " & nTimerID & " interval: " & Interval & "Parm: " & parm
