Detailed Description

Random number generator functions based on OpenSSL.

Function Documentation

◆ randchar()

char randchar ( void )

Returns a random ascii char

Returns: random char

◆ randrange()

unsigned randrange	(	unsigned	lower,
		unsigned	upper
	)

Generates an unsigned type random number in range (inclusive lower and exclusive upper bound)

Parameters

lower	lower boundary
upper	upper boundary

Returns: random number

◆ randstring()

void randstring	(	char *	buffer,
		size_t	len
	)

Fills the buffer with random ascii chars and NULL-terminates it.

Parameters

buffer	buffer to fill
len	length of buffer

Variable Documentation

◆ dict

const char* dict = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890"

static

Characterset to generate random strings from

◆ dict_len

unsigned dict_len = 62
