Description [src]

Finds a block of memory in another block of memory in a safe way.

Available since: 1.8.2

Parameters

haystack

Type: const guint8*

Destination buffer.

The data is owned by the caller of the function.

haystack_sz

Type: gsize

Maximum size of haystack, typically sizeof(haystack)

needle

Type: const guint8*

Source buffer.

The data is owned by the caller of the function.

needle_sz

Type: gsize

Maximum size of haystack, typically sizeof(needle)

offset

Type: gsize*

Offset in bytes needle has been found in haystack.

The argument will be set by the function.

The argument can be set to NULL by the function.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the function if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gboolean

TRUE if the needle was found in the haystack, FALSE otherwise.
