Q_IRAWMASK3
Fixed-point math functions which manipulate the integer data bits
Usage
#include <sys/qmath.h>
ITYPE
Q_IRAWMASK(QTYPE q);
ITYPE
Q_GIRAW(QTYPE q);
ITYPE
Q_GIABSVAL(QTYPE q);
ITYPE
Q_GIVAL(QTYPE q);
QTYPE
Q_SIVAL(QTYPE q, ITYPE iv);
Overview
Q_IRAWMASK() returns a q-specific bit mask for q's integer data bits.
Q_GIRAW() returns q's raw masked integer data bits.
Q_GIABSVAL() and Q_GIVAL() return the absolute and real values of q's integer data bits respectively.
Q_SIVAL() sets q's integer data bits to the value iv.
All of those functions operate on the following data types: s8q_t, u8q_t, s16q_t, u16q_t, s32q_t, u32q_t, s64q_t, and u64q_t, which are referred to generically as QTYPE. The ITYPE refers to the stdint(7) integer types.
For more details, see qmath(3).
Return values
Q_IRAWMASK(), Q_GIRAW(), Q_GIABSVAL() and Q_GIVAL() return their respective values as integers of the same underlying ITYPE as q.
Q_SIVAL() returns the value of q post change.
