New page

<pre>
BinaryContains( <binary-array>, <needle>, <start>, <length> )
</pre>

=== Description ===

Check if a binary variable contains a given byte or contains another binary variable .

=== Parameters ===

==== binary-array ====

The binary variable to use.

==== needle ====

A binary variable to find or a value to use as a byte

==== start ====

Position to start from.

If the start is a negative value the position will work backwards from the length of the binary.

==== length ====

Optional; How many bytes to count to before stopping the search.

Default is all remaining bytes;

If length is given and is negative, then that many bytes will be omitted from the end of binary (after the start position has been calculated when a start is negative).

If start denotes the position of this truncation or beyond, empty binary variable will be returned.

=== Return Value ===

Success: Returns true.

Failure: Returns false (On error or if there was no bytes were added).

=== Remarks ===

None.

=== Example ===

<syntaxhighlight lang="sputnik">
// Convert a string to binary
my $bin = Pack("A*", "Hello World!");
// Search for single chars
say BinaryContains($bin, @'A'); // false
say BinaryContains($bin, @'W'); // true
say BinaryContains($bin, @' '); // true
say BinaryContains($bin, @'@'); // false
say BinaryContains($bin, @'!'); // true
// Search for single bytes
say BinaryContains($bin, 0x20); // true
say BinaryContains($bin, 0x7F); // false
// Search for binary
say BinaryContains($bin, Pack("A*", "World")); // true
say BinaryContains($bin, Pack("A*", "Cat")); // false
</syntaxhighlight>
