| =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); |
| void DSA_SIG_get0(BIGNUM **pr, BIGNUM **ps, const DSA_SIG *sig); |
| |
| =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. |
| |
| DSA_SIG_get0() returns internal pointers the B<r> and B<s> values contained |
| in B<sig>. The values can then be examined or initialised. |
| |
| =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)>. Otherwise it returns a pointer |
| to the newly allocated structure. |
| |
| DSA_SIG_free() returns no value. |
