Function Documentation
| uint16_t randLIB_get_16bit | ( | void | ) |
Generate 16-bit random number.
- Parameters:
-
None
- Returns:
- 16-bit random number
Definition at line 56 of file linux/randLIB.c.
| uint32_t randLIB_get_32bit | ( | void | ) |
Generate 32-bit random number.
- Parameters:
-
None
- Returns:
- 16-bit random number
- Parameters:
-
None
- Returns:
- 32-bit random number
Definition at line 70 of file linux/randLIB.c.
| uint8_t randLIB_get_8bit | ( | void | ) |
Generate 8-bit random number.
- Parameters:
-
None
- Returns:
- 8-bit random number
Definition at line 42 of file linux/randLIB.c.
| int8_t randLIB_get_n_bytes_random | ( | uint8_t * | data_ptr, |
| uint8_t | eight_bit_boundary | ||
| ) |
Generate n-bytes random numbers.
- Parameters:
-
data_ptr pointer where random will be stored eight_bit_boundary how many bytes need random
- Returns:
- 0 process valid
- -1 Unsupported Parameters
- Parameters:
-
data_ptr pointer where random will be stored eight_bit_boundary how many bytes need random
- Returns:
- 0 process valid
- -1 Unsupported Parameters or failed to get random data.
Definition at line 87 of file linux/randLIB.c.
| uint16_t randLIB_get_random_in_range | ( | uint16_t | min, |
| uint16_t | max | ||
| ) |
Generate a random number within a range.
The result is linearly distributed in the range [min..max], inclusive.
- Parameters:
-
min minimum value that can be generated max maximum value that can be generated
Definition at line 112 of file linux/randLIB.c.
| uint32_t randLIB_randomise_base | ( | uint32_t | base, |
| uint16_t | min_factor, | ||
| uint16_t | max_factor | ||
| ) |
Randomise a base 32-bit number by a jitter factor.
The result is linearly distributed in the jitter range, which is expressed as fixed-point unsigned 1.15 values. For example, to produce a number in the range [0.75 * base, 1.25 * base], set min_factor to 0x6000 and max_factor to 0xA000.
Result is clamped to 0xFFFFFFFF if it overflows.
- Parameters:
-
base The base 32-bit value min_factor The minimum value for the random factor max_factor The maximum value for the random factor
Definition at line 150 of file linux/randLIB.c.
| void randLIB_seed_random | ( | void | ) |
This library is made for getting random numbers for Timing needs in protocols.
**not safe to use for security or cryptographic operations.** Init seed for Pseudo Random.
- Returns:
- None
