Sequences of pseudo-random numbers in GMP are generated using a variable of
type gmp_randstate_t
, which holds an algorithm selection and a current
state. Such a variable must be initialized by a call to one of the
gmp_randinit
functions, and can be seeded with one of the
gmp_randseed
functions.
The functions actually generating random numbers are described in Integer Random Numbers, and Miscellaneous Float Functions.
The older style random number functions don’t accept a gmp_randstate_t
parameter but instead share a global variable of that type. They use a
default algorithm and are currently not seeded (though perhaps that will
change in the future). The new functions accepting a gmp_randstate_t
are recommended for applications that care about randomness.
