Parameters

buf	buffer to check

Returns: true if the buffer's contents have changed

void buf_freeall	(	buf_T *	buf,
		int	flags
	)

buf_freeall() - free all things allocated for a buffer that are related to the file. Careful: get here with "curwin" NULL when exiting.

Parameters

Always considered 'nomodified'

Parameters

bufnr Buffer to switch to, or 0 to create a new buffer.

bool buf_valid ( buf_T * buf )

Check that "buf" points to a valid buffer in the buffer list.

Can be slow if there are many buffers, prefer using bufref_valid().

Parameters

buf	The buffer to check for.

buf_T* buflist_findnr ( int nr )

Find a file in the buffer list by buffer number.

int buflist_findpat	(	const char_u *	pattern,
		const char_u *	pattern_end,
		int	unlisted,
		int	diffmode,
		int	curtab_only
	)

Find file in buffer list by a regexp pattern. Return fnum of the found buffer. Return < 0 for error.

int buflist_getfile	(	int	n,
		linenr_T	lnum,
		int	options,
		int	forceit
	)

Get alternate file "n". Set linenr to "lnum" or altfpos.lnum if "lnum" == 0. Also set cursor column to altfpos.col if 'startofline' is not set. if (options & GETF_SETMARK) call setpcmark() if (options & GETF_ALT) we are jumping to an alternate file. if (options & GETF_SWITCH) respect 'switchbuf' settings when jumping

Return FAIL for failure, OK for success.

void buflist_getfpos ( void )

void buflist_list ( exarg_T * eap )

int buflist_name_nr	(	int	fnum,
		char_u **	fname,

	)

buf_T* buflist_new	(	char_u *	ffname,
		char_u *	sfname,
		linenr_T	lnum,
		int	flags
	)

Add a file name to the buffer list. If the same file name already exists return a pointer to that buffer. If it does not exist, or if fname == NULL, a new entry is created. If (flags & BLN_CURBUF) is true, may use current buffer. If (flags & BLN_LISTED) is true, add new buffer to buffer list. If (flags & BLN_DUMMY) is true, don't count it as a real buffer. If (flags & BLN_NEW) is true, don't use an existing buffer. If (flags & BLN_NOOPT) is true, don't copy options from the current buffer if the buffer already exists. This is the ONLY way to create a new buffer.

Parameters

ffname	full path of fname or relative
sfname	short fname or NULL
lnum	preferred cursor line
flags	BLN_ defines
bufnr

Returns: pointer to the buffer

char_u* buflist_nr2name	(	int	n,

void buflist_setfpos	(	buf_T *const	buf,
		win_T *const	win,
		linenr_T	lnum,
		colnr_T	col,
		bool	copy_options
	)

Set the line and column numbers for the given buffer and window

Parameters

[in,out]	buf	Buffer for which line and column are set.
[in,out]	win	Window for which line and column are set.
[in]	lnum	Line number to be set. If it is zero then only options are touched.
[in]	col	Column number to be set.
[in]	copy_options	If true save the local window option values.

bool bufref_valid ( bufref_T * bufref )

Return true if "bufref->br_buf" points to the same buffer as when set_bufref() was called and it is a valid buffer. Only goes through the buffer list if buf_free_count changed. Also checks if b_fnum is still the same, a :bwipe followed by :new might get the same allocated memory, but it's a different buffer.

Parameters

bufref Buffer reference to check for.

int build_stl_str_hl	(	win_T *	wp,
		char_u *	out,
		size_t	outlen,
		char_u *	fmt,
		int	use_sandbox,
		char_u	fillchar,
		int	maxwidth,
		struct stl_hlrec *	hltab,
		StlClickRecord *	tabtab
	)

Build a string from the status line items in "fmt". Return length of string in screen cells.

Normally works for window "wp", except when working for 'tabline' then it is "curwin".

Items are drawn interspersed with the text that surrounds it Specials: %-<wid>(xxx%) => group, %= => separation marker, %< => truncation Item: %-<minwid>.<maxwid><itemch> All but <itemch> are optional

If maxwidth is not zero, the string will be filled at any middle marker or truncated if too long, fillchar is used for all whitespace.

Parameters

wp	The window to build a statusline for
out	The output buffer to write the statusline to Note: This should not be NameBuff
outlen	The length of the output buffer
fmt	The statusline format string
use_sandbox	Use a sandboxed environment when evaluating fmt
fillchar	Character to use when filling empty space in the statusline
maxwidth	The maximum width to make the statusline
hltab	HL attributes (can be NULL)
tabtab	Tab clicks definition (can be NULL).

Returns: The final width of the statusline

void close_buffer	(	win_T *	win,
		buf_T *	buf,
		int	action,
		bool	abort_if_last
	)

Close the link to a buffer.

Parameters

win	If not NULL, set b_last_cursor.
buf
action	Used when there is no longer a window for the buffer. Possible values: 0 buffer becomes hidden DOBUF_UNLOAD buffer is unloaded DOBUF_DELETE buffer is unloaded and removed from buffer list DOBUF_WIPE buffer is unloaded and really deleted When doing all but the first one on the current buffer, the caller should get a new buffer very soon! The 'bufhidden' option can force freeing and deleting.
abort_if_last	If true, do not close the buffer if autocommands cause there to be only one window with this buffer. e.g. when ":quit" is supposed to close the window but autocommands close all other windows.

void col_print	(	char_u *	buf,
		size_t	buflen,
		int	col,
		int	vcol
	)

bool curbuf_reusable ( void )
