Macro Definition Documentation

#define SL_CLEAR_BIT ( val,
mask
) ((val) = ((val) & (~(mask))))

Clear specified bit(s) in a value.

SL_CLEAR_BIT()

Parameters
val Value to modify by clearing specified bit(s).
mask Mask of bits to clear.
Returns
Modified value with specified bit(s) clear.
Note
'val' & 'mask' SHOULD be unsigned integers.
'mask' SHOULD be cast with the same data type than 'val'.

#define SL_IS_ANY_BIT_CLEAR ( val,
mask
) ((((val) & (mask)) == (mask)) ? (false) : (true))

Determine if any specified bit(s) in a value are clear.

SL_IS_ANY_BIT_CLEAR()

Parameters
val Value to check for specified bit(s) clear.
mask Mask of bits to check if clear (see Note #2).
Returns
true, if ANY specified bit(s) are clear in value.
      false,  if ALL specified bit(s) are NOT clear in value.
Note
'val' & 'mask' SHOULD be unsigned integers.
NULL 'mask' allowed; returns 'false' since NO mask bits specified.

#define SL_IS_ANY_BIT_SET ( val,
mask
) ((((val) & (mask)) == 0u) ? (false) : (true))

SL_IS_ANY_BIT_SET()

Parameters
val Value to check for specified bit(s) set.
mask Mask of bits to check if set (see Note #2).
Returns
true, if ANY specified bit(s) are set in value.
      false, if ALL specified bit(s) are NOT set in value.
Note
'val' & 'mask' SHOULD be unsigned integers.
NULL 'mask' allowed; returns 'false' since NO mask bits specified.

SL_IS_BIT_CLEAR()

Parameters
val Value to check for specified bit(s) clear.
mask Mask of bits to check if clear.
Returns
true, if ALL specified bit(s) are clear in value.
      false, if ALL specified bit(s) are NOT clear in value.
Note
val' & 'mask' SHOULD be unsigned integers.
NULL 'mask' allowed; returns 'false' since NO mask bits specified.
