Function:   lcmaps_setArgValue
Description:
    Set the value of argType on the reserved place in values. 
    The place within values is determined by the place where argName is found

    argType: type of argument
    argcx:   number of arguments
    argvx:   array of arguments structures
Returns:
    0:  success
    -1: failure (could not find structure with name argName)
