=head1 NAME
|
|
DSA_SIG_new, DSA_SIG_free - allocate and free DSA signature objects
|
|
=head1 SYNOPSIS
|
|
#include <openssl/dsa.h>
|
|
DSA_SIG *DSA_SIG_new(void);
|
|
void DSA_SIG_free(DSA_SIG *a);
|
|
=head1 DESCRIPTION
|
|
DSA_SIG_new() allocates and initializes a B<DSA_SIG> structure.
|
|
DSA_SIG_free() frees the B<DSA_SIG> structure and its components. The
|
values are erased before the memory is returned to the system.
|
|
=head1 RETURN VALUES
|
|
If the allocation fails, DSA_SIG_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_SIG_free() returns no value.
