	)

void yy_delete_buffer

(

YY_BUFFER_STATE

b

)

void yy_flush_buffer

(

YY_BUFFER_STATE

b

)

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.

References yy_buffer_state::yy_at_bol, yy_buffer_state::yy_buf_pos, YY_BUFFER_NEW, yy_buffer_state::yy_buffer_status, yy_buffer_state::yy_ch_buf, YY_CURRENT_BUFFER, YY_END_OF_BUFFER_CHAR, yy_load_buffer_state, and yy_buffer_state::yy_n_chars.

YY_BUFFER_STATE yy_scan_buffer	(	char *	base,
		yy_size_t	size
	)

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

Returns:

the newly allocated buffer state object.

YY_BUFFER_STATE yy_scan_bytes	(	yyconst char *	yybytes,
		int	_yybytes_len
	)

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.

Returns:

the newly allocated buffer state object.

YY_BUFFER_STATE yy_scan_string

(

yyconst char *

yystr

)

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

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.
