Dynamically-sized array, displayed as text; no need to be null-terminated:
The parameters are:
-'int_type'::
- Integer C type. The size of this type determines the size of the
- integer/enumeration field.
-
-'float_type'::
- Float C type (`float` or `double`). The size of this type determines
- the size of the floating point number field.
+'count'::
+ Number of elements in array/sequence. This must be known at
+ compile time.
-'field_name'::
- Event field name (C identifier syntax, :not: a literal string).
+'enum_name'::
+ Name of an enumeration field previously defined with the
+ `TRACEPOINT_ENUM()` macro. See the
+ <<tracepoint-enum,`TRACEPOINT_ENUM()` usage>> section for more
+ information.
'expr'::
C expression resulting in the field's value. This expression can
of a given tracepoint are defined in the `TP_ARGS()` macro (see
the <<creating-tp,Creating a tracepoint provider>> section above).
-'count'::
- Number of elements in array/sequence. This must be known at
- compile time.
+'field_name'::
+ Event field name (C identifier syntax, :not: a literal string).
-'len_type'::
- Unsigned integer C type of sequence's length.
+'float_type'::
+ Float C type (`float` or `double`). The size of this type determines
+ the size of the floating point number field.
+
+'int_type'::
+ Integer C type. The size of this type determines the size of the
+ integer/enumeration field.
'len_expr'::
C expression resulting in the sequence's length. This expression
can use one or more arguments passed to the tracepoint.
+'len_type'::
+ Unsigned integer C type of sequence's length.
+
'prov_name'::
Tracepoint provider name. This must be the same as the tracepoint
provider name used in a previous field definition.
-'enum_name'::
- Name of an enumeration field previously defined with the
- `TRACEPOINT_ENUM()` macro. See the
- <<tracepoint-enum,`TRACEPOINT_ENUM()` usage>> section for more
- information.

The `_nowrite` versions omit themselves from the recorded trace, but are
otherwise identical. Their primary purpose is to make some of the
event context available to the event filters without having to commit
