YY_BUFFER_STATE stat_create_buffer ( FILE *  file,
int  size 
)

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.
Returns:
the allocated buffer state.

void stat_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.

YY_BUFFER_STATE stat_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.

Setup the input buffer state to scan the given bytes.

The next call to statlex() will scan from a copy of bytes.

Parameters:
bytes the byte buffer to scan
len the number of bytes in the buffer pointed to by bytes.

str 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 stat_scan_bytes() instead.
