[c.math.rand] (original) (raw)
Remarks:The implementation may specify that particular library functions may callrand.
It is implementation-defined whether the rand function may introduce data races ([res.on.data.races]).
[ Note
:
The other random number generation facilities in this document ([rand]) are often preferable to rand, because rand's underlying algorithm is unspecified.
Use of rand therefore continues to be non-portable, with unpredictable and oft-questionable quality and performance.
