◆ vlc_drand48()
| double vlc_drand48 | ( | void | ) |
PRNG uniformly distributed between 0.0 and 1.0 with 48-bits precision.
- Note
- Contrary to POSIX drand48(), this function is thread-safe.
- Warning
- Series generated by this function are not reproducible. Use erand48() if you need reproducible series.
- Returns
- a double value within [0.0, 1.0] inclusive
References erand48(), init_rand48(), rand48, vlc_mutex_lock(), and vlc_mutex_unlock().
◆ vlc_lrand48()
| long vlc_lrand48 | ( | void | ) |
PRNG uniformly distributed between 0 and 2^32 - 1.
- Note
- Contrary to POSIX lrand48(), this function is thread-safe.
- Warning
- Series generated by this function are not reproducible. Use nrand48() if you need reproducible series.
- Returns
- an integral value within [0.0, 2^32-1] inclusive

◆ vlc_mrand48()
| long vlc_mrand48 | ( | void | ) |
PRNG uniformly distributed between -2^32 and 2^32 - 1.
- Note
- Contrary to POSIX mrand48(), this function is thread-safe.
- Warning
- Series generated by this function are not reproducible. Use jrand48() if you need reproducible series.
- Returns
- an integral value within [-2^32, 2^32-1] inclusive
