DESCRIPTIONQ_IFRAWMASK () returns a q-specific
bit mask for q's combined integer and fractional data
bits.
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 VALUESQ_IFRAWMASK (), Q_IFVALIMASK (),
Q_IFVALFMASK (), Q_GIFABSVAL (),
Q_GIFVAL (), Q_GIFRAW (),
Q_GIFABSVAL () and Q_GIFVAL ()
return their respective values as integers of the same underlying ITYPE as
q.
