Subject: output/srzip: decorate read pointer as const for awareness
X-Git-Url: https://sigrok.org/gitaction?a=commitdiff_plain;h=201bd256a8aa85035423023914889fe9f5db52db;p=libsigrok.git

output/srzip: decorate read pointer as const for awareness

Recipients of sample data as received from the data feed should consider
this data read-only, they are handed a reference to a message which is
also sent to other recipients.

Add the 'const' decoration in the output/srzip module to raise awareness
during future maintenance.
