=head1 NAME
|
|
|
|
rand_bytes_ex, rand_priv_bytes_ex
|
|
- internal random number routines
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include "internal/rand_int.h"
|
|
|
|
int rand_bytes_ex(OPENSSL_CTX *ctx, unsigned char *buf, int num);
|
|
int rand_priv_bytes_ex(OPENSSL_CTX *ctx, unsigned char *buf, int num);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
rand_bytes_ex() and rand_priv_bytes_ex() are the equivalent of RAND_bytes() and
|
|
RAND_priv_bytes() in the public API except that they both take an additional
|
|
I<ctx> parameter.
|
|
The DRBG used for the operation is the public or private DRBG associated with
|
|
the specified I<ctx>. The parameter can be NULL, in which case
|
|
the default library ctx is used.
|
|
If the default RAND_METHOD has been changed then for compatibility reasons the
|
|
RAND_METHOD will be used in preference and the DRBG of the library context
|
|
ignored.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
rand_bytes_ex() and rand_bytes_priv_ex() return 0 or less on error or 1 on
|
|
success.
