Here is the caller graph for this function:

static bool ms_check_version ( Meta_Info server)
static

This checks the servers sc_version and cs_version to see if they are compatible.

Parameters
entryentry number in the metaservers array to check.
Returns
1 if this entry is compatible, 0 if it is not. Note that this can only meaningfully check metaserver2 data - metaserver1 doesn't include protocol version number, so treats all of those as OK.
