Description [src]

Compares the buffers for equality.

Available since: 1.8.2

Parameters

Type: const guint8*

A buffer.

The data is owned by the caller of the function.

buf1_sz

Type: gsize

Sizeof buf1

buf1_offset

Type: gsize

Offset into buf1

buf2

Type: const guint8*

Another buffer.

The data is owned by the caller of the function.

buf2_sz

Type: gsize

Sizeof buf2

buf2_offset

Type: gsize

Offset into buf1

n

Type: gsize

Number of bytes to compare from buf1+buf1_offset from.

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 buf1 and buf2 are identical.
