Function Documentation

YY_BUFFER_STATE ao_create_buffer	(	FILE *	file,
		int	size
	)

void ao_delete_buffer

(

YY_BUFFER_STATE

b

)

void ao_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, and yy_buffer_state::yy_n_chars.

YY_BUFFER_STATE ao_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.

References ao_switch_to_buffer(), aoalloc(), yy_buffer_state::yy_at_bol, yy_buffer_state::yy_buf_pos, yy_buffer_state::yy_buf_size, YY_BUFFER_NEW, yy_buffer_state::yy_buffer_status, yy_buffer_state::yy_ch_buf, YY_END_OF_BUFFER_CHAR, YY_FATAL_ERROR, yy_buffer_state::yy_fill_buffer, yy_buffer_state::yy_input_file, yy_buffer_state::yy_is_interactive, yy_buffer_state::yy_is_our_buffer, and yy_buffer_state::yy_n_chars.

Referenced by ao_scan_bytes().

YY_BUFFER_STATE ao_scan_bytes	(	yyconst char *	bytes,
		int	len
	)

Setup the input buffer state to scan the given bytes. The next call to aolex() 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 ao_scan_string

(

yyconst char *

yy_str

)

Setup the input buffer state to scan a string. The next call to aolex() 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 ao_scan_bytes() instead.

void aopush_buffer_state

(

YY_BUFFER_STATE

new_buffer

Pushes the new state onto the stack. The new state becomes the current state. This function will allocate the stack if necessary.

Parameters:

new_buffer

The new state.
