DSA_SIG_new 3 2003-07-24 0.9.9-dev OpenSSL

### NAME

DSA_SIG_new, DSA_SIG_free - allocate and free DSA signature objects

### LIBRARY

libcrypto, -lcrypto

### SYNOPSIS

     #include

     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(3). Otherwise it returns a pointer to the newly allocated structure.

DSA_SIG_free() returns no value.

### SEE ALSO

### HISTORY

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