[asterisk-bugs] [JIRA] (ASTERISK-27659) Output from rawman truncated if output is long enough

[Bojan Nemčić (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-27659?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bojan Nemčić updated ASTERISK-27659:
------------------------------------

    Description: 
Output from rawman is truncated if the output of the requested action is long enough (in my case >4100 bytes, but I cannot confirm if this is a constant on all systems).

Seems to be caused by the wrong argument order passed to {{lseek}}, patch attached.
