fn() defaultRng
Return the default random number generator object of a given type.

Defined in <seqan/random.h>
Signature TRng defaultRng<TRng>();

Template Parameters

TRng The random number generator type to construct.

Return Values

TRng Default random number generator of the given type TRng.

Detailed Description

Remarks

The random number generator will be default constructed, i.e. with the default seed.

This function is NOT thread-safe! Also, data structures and functions using defaultRng are not thread-safe. Data structures using global random number generator state should use pointers. This way, the random number generator state to be used can be set to be thread-local.

Data Races

If not stated otherwise, concurrent invocation is not guaranteed to be thread-safe.
