Q_IFVALIMASK() and Q_IFVALFMASK() return q, Ns, -specific bit masks for the integer and fractional bits of q, Ap, s combined integer and fractional data bits value, i.e., are applicable to the values returned by Q_GIFABSVAL() and Q_GIFVAL().
Q_GIFRAW() returns q, Ap, s raw masked integer/fractional data bits.
Q_GIFABSVAL() and Q_GIFVAL() return the absolute and real values of q, Ap, s integer/fractional data bits respectively.
Q_SIFVAL() sets q, Ap, s combined integer/fractional data bits to the value ifv, whereas Q_SIFVALS() independently sets q, Ap, s integer and fractional data bits to the separate values iv and fv.
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).
Q_SIFVAL() and Q_SIFVALS() return the value of q post change.

| “ | Ken Thompson has an automobile which he helped design. Unlike most automobiles, it has neither speedometer, nor gas gauge, nor any of the other numerous idiot lights which plague the modern driver. Rather, if the driver makes a mistake, a giant “?” lights up in the center of the dashboard. “The experienced driver,” says Thompson, “will usually know what's wrong.” | ” |
