# fn() getTerminalSize
Retrieve size of terminal.

Defined in | <seqan/misc/terminal.h>
Signature | `bool getTerminalSize(cols, rows);`

## Parameters

`cols` | An `unsigned` value the column count is written to.
`rows` | An `unsigned` value the row count is written to.

## Return Values

`bool` | true on success, false otherwise.

## Detailed Description

### Remarks

On Windows, `rows` contains the number o frows in the terminal buffer, not the window.

### Examples

The following demonstrates the usage.

    #include <iostream>

    #include <seqan/misc/terminal.h>

    using namespace seqan;

    int main()
    {
        // Get terminal size and print it to stdout.
        unsigned cols = 0, rows = 0;
        getTerminalSize(cols, rows);
        std::cout << "cols == " << cols << ", rows == " << rows << "\n";

        return 0;
    }
