[systemd-devel] [PATCH 1/2] man/sd_journal_next: fix argument in example

[Christian Hesse]

From: Christian Hesse <mail at eworm.de>

The example does not compile, it fails with:

error: passing argument 3 of ‘sd_journal_get_data’ from incompatible
pointer type

Cast to (const void **) to avoid this.
