Macros | |
| #define | OSRTBYTEARRAYSIZE(numbits) ((numbits+7)/8) |
| This macro is used to calculate the byte array size required to hold the given number of bits. | |
Functions | |
| EXTERNRT OSUINT32 | rtxGetBitCount (OSUINT32 value) |
| This function returns the minimum size of the bit field required to hold the given integer value. More... | |
| EXTERNRT int | rtxSetBit (OSOCTET *pBits, OSSIZE numbits, OSSIZE bitIndex) |
| This function sets the specified zero-counted bit in the bit string. More... | |
| EXTERNRT OSUINT32 | rtxSetBitFlags (OSUINT32 flags, OSUINT32 mask, OSBOOL action) |
| This function sets one or more bits to TRUE or FALSE in a 32-bit unsigned bit flag set. More... | |
| EXTERNRT int | rtxClearBit (OSOCTET *pBits, OSSIZE numbits, OSSIZE bitIndex) |
| This function clears the specified zero-counted bit in the bit string. More... | |
| EXTERNRT OSBOOL | rtxTestBit (const OSOCTET *pBits, OSSIZE numbits, OSSIZE bitIndex) |
| This function tests the specified zero-counted bit in the bit string. More... | |
| EXTERNRT OSSIZE | rtxLastBitSet (const OSOCTET *pBits, OSSIZE numbits) |
| This function returns the zero-counted index of the last bit set in a bit string. More... | |
| EXTERNRT int | rtxCheckBitBounds (OSCTXT *pctxt, OSOCTET **ppBits, OSSIZE *pNumocts, OSSIZE minRequiredBits, OSSIZE preferredLimitBits) |
| Check whether the given bit string is large enough, and expand it if necessary. More... | |
| EXTERNRT int | rtxZeroUnusedBits (OSOCTET *pBits, OSSIZE numbits) |
| This function zeros unused bits at the end of the given bit string. More... | |
| EXTERNRT int | rtxCheckUnusedBitsZero (const OSOCTET *pBits, OSSIZE numbits) |
| This function checks to see if unused bits at the end of the given bit string are zero. More... | |
