nvim_buf_call({buffer}, {fun})                               *nvim_buf_call()*
    Call a function with buffer as temporary current buffer.

    This temporarily switches current buffer to "buffer". If the current
    window already shows "buffer", the window is not switched. If a window
    inside the current tabpage (including a float) already shows the buffer,
    then one of those windows will be set as current window temporarily.
    Otherwise a temporary scratch window (called the "autocmd window" for
    historical reasons) will be used.

    This is useful e.g. to call Vimscript functions that only work with the
    current buffer/window currently, like `jobstart(…, {'term': v:true})`.

    Attributes: ~
        Lua |vim.api| only
        Since: 0.5.0

    Parameters: ~
      • {buffer}  Buffer id, or 0 for current buffer
      • {fun}     Function to call inside the buffer (currently Lua callable
                  only)

    Return: ~
        Return value of function.

nvim_buf_del_keymap({buffer}, {mode}, {lhs})           *nvim_buf_del_keymap()*
    Unmaps a buffer-local |mapping| for the given mode.

    Attributes: ~
        Since: 0.4.0

    Parameters: ~
      • {buffer}  Buffer id, or 0 for current buffer

nvim_buf_del_mark({buffer}, {name})                      *nvim_buf_del_mark()*
    Deletes a named mark in the buffer. See |mark-motions|.

    Note: ~
      • only deletes marks set in the buffer, if the mark is not set in the
        buffer it will return false.

    Attributes: ~
        Since: 0.6.0

    Parameters: ~
      • {buffer}  Buffer to set the mark on
      • {name}    Mark name

    Return: ~
        true if the mark was deleted, else false.

nvim_buf_del_var({buffer}, {name})                        *nvim_buf_del_var()*
    Removes a buffer-scoped (b:) variable

    Attributes: ~
        Since: 0.1.0

    Parameters: ~
      • {buffer}  Buffer id, or 0 for current buffer
      • {name}    Variable name

nvim_buf_delete({buffer}, {opts})                          *nvim_buf_delete()*
    Deletes a buffer and its metadata (like |:bwipeout|).

    To get |:bdelete| behavior, reset 'buflisted' and pass `unload=true`: >lua
        vim.bo.buflisted = false
        vim.api.nvim_buf_delete(0, { unload = true })

    Parameters: ~
      • {buffer}  Buffer id, or 0 for current
