It provides thread, timers, semaphores, mutexes and memory pool management APIs as well as random API.
Function Documentation
| palStatus_t pal_osRandom32bit | ( | uint32_t * | randomInt | ) |
Generate a 32-bit random number.
- Parameters
-
[out] randomInt A 32-bit buffer to hold the generated number.
- Note
pal_init()MUST be called before this function.-
If non-volatile entropy is expected, the entropy must be in storage when this function is called. Non-volatile entropy may be injected using
pal_plat_osEntropyInject().
- Returns
- PAL_SUCCESS on success, a negative value indicating a specific error code in case of failure.
| palStatus_t pal_osRandomBuffer | ( | uint8_t * | randomBuf, |
| size_t | bufSizeBytes | ||
| ) |
Generate random number into given buffer with given size in bytes.
- Parameters
-
[out] randomBuf A buffer to hold the generated number. [in] bufSizeBytes The size of the buffer and the size of the required random number to generate.
- Note
pal_init()MUST be called before this function.-
If non-volatile entropy is expected, the entropy must have been injected before this function is called. If entropy has not been injected to non-volatile memory, us
pal_plat_osEntropyInject().
- Returns
- PAL_SUCCESS on success, a negative value indicating a specific error code in case of failure.
