X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=7cb9889f780a78f728c10717625e288a20ea69cb;p=sigrok-cli.git

srd: Every callback should have a 'void *' parameter.

This is required in various situations and for various lib users,
especially so GUIs which might want to pass specific info via this
mechanism.
