Function Documentation

UINT8 bitrev (  UINT8  b  )  [inline]
 

< GENERATING_DOXYGEN_OUTPUT Reverse order of bits in a single byte.

Definition at line 222 of file membuf.h.

void bitrevlin (  UINT8 *  buf,
int  numbytes
) 
 

Reverse bits for array.

int getbit (  const UINT8 *  array,
INT32  index
)  [inline]
 

Get a value from a bit array.

Returns:
0 or 1.
Parameters:
array  Bit array
index  Index into array

Definition at line 242 of file membuf.h.

int getbitn (  const UINT8 *  array,
INT32  index
)  [inline]
 

Get a value from a bit array, returns 0 if array is NULL.

Returns:
0 or 1 (0 if array is NULL).
Parameters:
array  Bit array, can be NULL
index  Index into array

Definition at line 252 of file membuf.h.

void memswap (  void *  vb1,
void *  vb2,
int  count
)  [inline]
 

Swap data in two buffers.

Definition at line 287 of file membuf.h.

void packbits (  UINT8 *  dest,
UINT8 *  source,
int  count
) 
 

Pack TRUE/FALSE values from 8-bit array into bit array with least-significant bit as first bit.

Non-zero values in the 8-bit array will be written as '1', zero values will be written as '0'.

void packbitsr (  UINT8 *  dest,
UINT8 *  source,
int  count
) 
 

Pack TRUE / FALSE values from 8-bit array into bit array with MOST-significannt bit as first bit.

Non-zero values in the 8-bit array will be written as '1', zero values will be written as '0'.

void putbit (  UINT8 *  array,
INT32  index,
int  value
)  [inline]
 

Set entry in a bit array to a specified value.

Parameters:
array  Bit array
index  Index into array
value  Value to set to (any non-zero value assumed to be 1)

Definition at line 336 of file membuf.h.

void revbuffer (  void *  vbuf,
int  cols
) 
 

Reverse the order of values in UINT8 array.
