yy_create_buffer()

YY_BUFFER_STATE yy_create_buffer	(	FILE *	file,
		int	size,
		yyscan_t	yyscanner
	)

Allocate and initialize an input buffer state.

Parameters

file	A readable stream.
size	The character buffer size in bytes. When in doubt, use YY_BUF_SIZE.
yyscanner	The scanner object.

Returns

the allocated buffer state.

yy_delete_buffer()

void yy_delete_buffer	(	YY_BUFFER_STATE	b,
		yyscan_t	yyscanner
	)

Destroy the buffer.

Parameters

b	a buffer created with yy_create_buffer()
yyscanner	The scanner object.

yy_flush_buffer()

void yy_flush_buffer	(	YY_BUFFER_STATE	b,
		yyscan_t	yyscanner
	)

Discard all buffered characters. On the next scan, YY_INPUT will be called.

Parameters

b	the buffer state to be flushed, usually YY_CURRENT_BUFFER.
yyscanner	The scanner object.

yy_scan_buffer()

YY_BUFFER_STATE yy_scan_buffer	(	char *	base,
		yy_size_t	size,
		yyscan_t	yyscanner
	)

Setup the input buffer state to scan directly from a user-specified character buffer.

Parameters

base	the character buffer
size	the size in bytes of the character buffer
yyscanner	The scanner object.

Returns

the newly allocated buffer state object.

yy_scan_bytes()

YY_BUFFER_STATE yy_scan_bytes	(	yyconst char *	yybytes,
		yy_size_t	_yybytes_len,
		yyscan_t	yyscanner
	)

Setup the input buffer state to scan the given bytes. The next call to yylex() will scan from a copy of bytes.

Parameters

yybytes	the byte buffer to scan
_yybytes_len	the number of bytes in the buffer pointed to by bytes.
yyscanner	The scanner object.

Returns

the newly allocated buffer state object.

yy_scan_string()

YY_BUFFER_STATE yy_scan_string	(	yyconst char *	yystr,
		yyscan_t	yyscanner
	)

Setup the input buffer state to scan a string. The next call to yylex() will scan from a copy of str.

Parameters

yystr	a NUL-terminated string to scan
yyscanner	The scanner object.

Returns

the newly allocated buffer state object.

Note

If you want to scan bytes that may contain NUL values, then use yy_scan_bytes() instead.

yy_switch_to_buffer()

void yy_switch_to_buffer	(	YY_BUFFER_STATE	new_buffer,
		yyscan_t	yyscanner
	)

Switch to a different input buffer.

Parameters

new_buffer	The new input buffer.
yyscanner	The scanner object.

yyalloc()

void * yyalloc	(	yy_size_t	size,
