DESCRIPTION <\/a> <\/h2>\n

These functions are the reentrant analogs of the functions described in drand48<\/b>(3). Instead of modifying the global random generator state, they use the supplied data buffer<\/i>.<\/p>\n

Before the first use, this struct must be initialized, for example, by filling it with zeros, or by calling one of the functions srand48_r<\/b>(), seed48_r<\/b>(), or lcong48_r<\/b>().<\/p>\n

RETURN VALUE <\/a> <\/h2>\n

The return value is 0.<\/p>\n

CONFORMING TO <\/a> <\/h2>\n

These functions are GNU extensions and are not portable.<\/p>\n
