The first prototype is when linked against libmcrypt 2.2.x, the
second when linked against libmcrypt 2.4.x or 2.5.x.
mcrypt_get_block_size is used to get the
size of a block of the specified cipher (in
combination with an encryption mode).
It is more useful to use the mcrypt_enc_get_block_size
function as this uses the resource returned by
mcrypt_module_open.
&reftitle.parameters;
cipher
One of the MCRYPT_ciphername constants or the name
of the algorithm as string.
module
The module.
&reftitle.returnvalues;
Gets the block size, as an integer.
