If <i>hdr</i> is a dynamic shared library, its segments are relocated - by <i>base</i> before being mapping. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - If <i>hdr</i> is a core file, there is one segment named <i>core</i> for each - contiguous section of memory recorded in the core file. There - are often quite a few of these, as most operating systems omit - clean memory pages when writing core files (Mac OS X is the only - exception among the supported systems). Because core files - have such holes, it is typically necessary to construct the core - map by calling <i>mapfile</i> on the executable and then calling it again - on the core file. Newly-added segments are mapped on top of existing - segments, so this arrangement will use the core file for the segments - it contains but fall back to the executable for the - rest. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Unmapfile</i> removes the mappings in <i>map</i> corresponding to <i>hdr</i>. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Mapproc</i> attaches to a running program and adds its segments to - the given map.
