Function getTimeoutFromObjectOrReply

src/timeout.cpp:166–192

Get a timeout value from an object and store it into 'timeout'. * The final timeout is always stored as milliseconds as a time where the * timeout will expire, however the parsing is performed according to * the 'unit' that can be seconds or milliseconds. * * Note that if the timeout is zero (usually from the point of view of * commands API this means no timeout) the value stored into 'timeo

 * commands API this means no timeout) the value stored into 'timeout'
