# 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.

# RETURN VALUES

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

`DSA_SIG_free()` returns no value.

# SEE ALSO

dsa, ERR_get_error, DSA_do_sign

# HISTORY

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