Hi, I'm looking for a function or a procedure that tries to allocate memory and return nil on failure.
GetMem seems to be a good candidate but it doesn't works as expected. The FreePascal documentations (http://www.freepascal.org/docs-html/rtl/system/getmem.html) tells that it returns nil on failure but it raises an out of memory exception (may be bug ???) when I try to allocates too much memory on linux (I haven't try on windows). Since my code is in fpc mode I can't catch the exeption. I know that there is a ReturnNilIfGrowHeapFails variable but this changes the behaviour of the all memory allocation system... I think I can do something like the following code but I fear it's not thread safe. function GetMemOrNil(size: PtrInt): pointer; var tmp : boolean; begin tmp:=ReturnNilIfGrowHeapFails; ReturnNilIfGrowHeapFails:=true; GetMemOrNil:=GetMem(size); ReturnNilIfGrowHeapFails:=tmp; end; Yann Ps : Sorry for poor english. I hope you can understand me. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
