Determines if all the specified bits in a value are set according to a specified bit mask.
Files
lib_def.h
Prototype
DEF_BIT_IS_SET(val, mask);
Arguments
val
Value to test if the specified bits are set.
mask
Mask of bits to check if set in the value.
Returned Value
DEF_YES
If all the bits in the bit mask a reset in val;
DEF_NO
if all the bits in the bit mask are not set in val.
Required Configuration
None.
Notes / Warnings
val and mask should be unsigned integers. NULL mask (i.e., mask of value 0) allowed; returns DEF_NO since no mask bits specified.
Example Usage
CPU_INT16U flags;
CPU_INT16U flags_mask;
CPU_INT16U flags_set;
flags = 0x0369u;
flags_mask = DEF_BIT_08 | DEF_BIT_09;
flags_set = DEF_BIT_IS_SET(flags, flags_mask);
