=pod =head1 NAME DSA_SIG_new, DSA_SIG_free - allocate and free DSA signature objects =head1 SYNOPSIS #include DSA_SIG *DSA_SIG_new(void); void DSA_SIG_free(DSA_SIG *a); void DSA_SIG_get0(BIGNUM **pr, BIGNUM **ps, DSA_SIG *sig); =head1 DESCRIPTION DSA_SIG_new() allocates and initializes a B structure. DSA_SIG_free() frees the B structure and its components. The values are erased before the memory is returned to the system. DSA_SIG_get0() returns internal pointers the B and B values contained in B. The values can then be examined or initialised. =head1 RETURN VALUES If the allocation fails, DSA_SIG_new() returns B and sets an error code that can be obtained by L. Otherwise it returns a pointer to the newly allocated structure. DSA_SIG_free() returns no value. =head1 SEE ALSO L, L, L =cut
