NAME

DSA_SIG_new, DSA_SIG_free — allocate and free DSA signature objects

SYNOPSIS

#include <openssl/dsa.h>

DSA_SIG *
DSA_SIG_new(void);

void
DSA_SIG_free(DSA_SIG *a);

DESCRIPTION

DSA_SIG_new() allocates and initializes a DSA_SIG structure.

DSA_SIG_free() frees the DSA_SIG structure and its components. The values are erased before the memory is returned to the system. If a is a NULL pointer, no action occurs.

RETURN VALUES

If the allocation fails, DSA_SIG_new() returns NULL and sets an error code that can be obtained by ERR_get_error(3). Otherwise it returns a pointer to the newly allocated structure.

HISTORY

DSA_SIG_new() and DSA_SIG_free() were added in OpenSSL 0.9.3.
