@CHIP-RTOS C Library - TCP/IP API

Crypt_Random_Bytes

Generate a stream of pseudo random bytes.

int far Crypt_Random_Bytes (
             unsigned char far *buf,
             unsigned int length ) ;

Parameters

buf

[out]   The random data will be written here.

length

[in]   Number of bytes to generate.

Return Value

0 constant (provisional error code)

Comments

This function uses the psuedo random number generator provided in hardware.

All bytes generataed will be non-zero.

RTOS API

On the first call, this library function invokes a software interrupt which modifies the code at the calling site inside your application program.   A direct FAR JMP into the @CHIP-RTOS-x86 implementation for this function is installed so that on return and on any subsequent calls to this API this dynamic link reaches the function's implementation directly.
