My apologies for this somewhat noob question but I'm not all that up to speed with MQL and reading through the documentation I see things like:-

Parameters
ticket

[in] Order index or order ticket depending on the second parameter.

select

[in] Selecting flags. It can be any of the following values:

SELECT_BY_POS - index in the order pool,
SELECT_BY_TICKET - index is order ticket.

My questions what does the [in] mean?


Thanks in advance.

you, have to provide this parameter (information) for the function, Unlike [out] u receive this parameter from the function

Example

bool  TextGetSize(
   const string       text,          // text string
   uint&               width,        // buffer width in pixels
   uint&               height        // buffer height in pixels
   );

Parameters

text

[in] String, for which length and width should be obtained.

width

[out] Input parameter for receiving width.

height

[out] Input parameter for receiving height.
