Q_IRAWMASK(3) BSD Library Functions Manual Q_IRAWMASK(3) NAME Q_IRAWMASK, Q_GIRAW, Q_GIABSVAL, Q_GIVAL, Q_SIVAL -- fixed-point math functions which manipulate the integer data bits SYNOPSIS #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); DESCRIPTION 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 in- teger 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 respec- tive values as integers of the same underlying ITYPE as q. Q_SIVAL() returns the value of q post change.
