=head1 NAME
|
|
|
|
DSA_new, DSA_free - allocate and free DSA objects
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/dsa.h>
|
|
|
|
DSA* DSA_new(void);
|
|
|
|
void DSA_free(DSA *dsa);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
DSA_new() allocates and initializes a B<DSA> structure. It is equivalent to
|
|
calling DSA_new_method(NULL).
|
|
|
|
DSA_free() frees the B<DSA> structure and its components. The values are
|
|
erased before the memory is returned to the system.
|
|
If B<dsa> is NULL nothing is done.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
If the allocation fails, DSA_new() returns B<NULL> and sets an error
|
|
code that can be obtained by
|
|
L<ERR_get_error(3)|ERR_get_error(3)>. Otherwise it returns a pointer
|
|
to the newly allocated structure.
|
|
|
|
DSA_free() returns no value.
