nanoid — generate
a Nano ID
#include
<nanoid.h>
int
nanoidgen(char
*buffer, size_t
length);
NANOIDLEN expands to the default Nano ID
length of 21.
nanoidgen()
fills the buffer with a Nano ID of the specified length up to
GETENTROPY_MAX (256) and returns the return value of
getentropy(3).
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the error.
