If <parameter>p</parameter> is not <constant>NULL</constant>, it should contain
a pointer to an appropriate object. For example, if <parameter>type</parameter>
is <constant>'y'</constant>, the object passed in <parameter>p</parameter>
- should have type <code>uint8_t *</code>. If <parameter>type</parameter> is
+ should have type <type>uint8_t *</type>. If <parameter>type</parameter> is
<constant>'s'</constant>, the object passed in <parameter>p</parameter> should
- have type <code>const char **</code>. Note that, if the basic type is a pointer
- (e.g., <code>const char *</code> in the case of a string), the pointer is only
+ have type <type>const char **</type>. Note that, if the basic type is a pointer
+ (e.g., <type>const char *</type> in the case of a string), the pointer is only
borrowed and the contents must be copied if they are to be used after the end
of the messages lifetime. Similarly, during the lifetime of such a pointer, the
message must not be modified. See the table below for a complete list of allowed
