#### limit parameter <a id="cpp.embed.param.limit">[[cpp.embed.param.limit]]</a>

+
An *embed-parameter* of the form `limit (` *pp-balanced-token-seq* `)`
|
| 4 |
+
specifies the maximum possible number of elements in the comma-delimited
|
| 5 |
+
list. It shall appear at most once in the *embed-parameter-seq*. The
|
| 6 |
+
preprocessing token `defined` shall not appear in the
|
| 7 |
+
*pp-balanced-token-seq*.
|
| 8 |
+
|
| 9 |
+
The *pp-balanced-token-seq* is evaluated as a *constant-expression*
|
| 10 |
+
using the rules as described in conditional inclusion [[cpp.cond]], but
|
| 11 |
+
without being processed as in normal text an additional time.
|
| 12 |
+
|
| 13 |
+
[*Example 1*:
|
| 14 |
+
|
| 15 |
+
``` cpp
|
| 16 |
+
#undef DATA_LIMIT
|
| 17 |
+
#if __has_embed(<data.dat> limit(DATA_LIMIT))
|
| 18 |
+
#endif
|
| 19 |
+
```
|
| 20 |
+
|
| 21 |
+
is equivalent to:
|
| 22 |
+
|
| 23 |
+
``` cpp
|
| 24 |
+
#if __has_embed(<data.dat> limit(0))
|
| 25 |
+
#endif
|
| 26 |
+
```
|
| 27 |
+
|
| 28 |
+
— *end example*]
|
| 29 |
+
|
| 30 |
+
[*Example 2*:
|
| 31 |
+
|
| 32 |
+
``` cpp
|
| 33 |
+
#embed <data.dat> limit(__has_include("a.h"))
|
| 34 |
+
|
| 35 |
+
#if __has_embed(<data.dat> limit(__has_include("a.h")))
|
| 36 |
+
// ill-formed: __has_include[cpp.cond] cannot appear here
|
| 37 |
+
#endif
|
| 38 |
+
```

|
| 41 |
+
|
| 42 |
+
The *constant-expression* shall be an integral constant expression whose
|
| 43 |
+
value is greater than or equal to zero. The resource-count
|
| 44 |
+
[[cpp.embed.gen]] becomes implementation-resource-count, if the value of
|
| 45 |
+
the *constant-expression* is greater than implementation-resource-count;
|
| 46 |
+
otherwise, the value of the *constant-expression*.
|
| 47 |
+
|
| 48 |
+
[*Example 3*:
|
| 49 |
+
|
| 50 |
+
``` cpp
|
| 51 |
+
constexpr unsigned char sound_signature[] = {
|
| 52 |
+
// a hypothetical resource capable of expanding to four or more elements
|
| 53 |
+
#embed <sdk/jump.wav> limit(2+2)
|
| 54 |
+
};
|
| 55 |
+
|
| 56 |
+
static_assert(sizeof(sound_signature) == 4); // OK
|
| 57 |
+
```
