Return a |List| with the lines starting from {lnum} to {end} (inclusive) in the buffer {expr}. If {end} is omitted, a |List| with only the line {lnum} is returned.

For the use of {expr}, see |bufname()| above.

For {lnum} and {end} "$" can be used for the last line of the buffer. Otherwise a number must be used.

When {lnum} is smaller than 1 or bigger than the number of lines in the buffer, an empty |List| is returned.

When {end} is greater than the number of lines in the buffer, it is treated as {end} is set to the number of lines in the buffer. When {end} is before {lnum} an empty |List| is returned.

This function works only for loaded buffers. For unloaded and non-existing buffers, an empty |List| is returned.

Example: > :let lines = getbufline(bufnr("myfile"), 1, "$")
