I'm experimenting with steamworks, trying to retrieve stats for a game via sourcepawn.

The problem is the buffer size I need to store all the stats. Everything I've tried hasn't worked so far.

char sBody[20000];
[SM] Exception reported: Not enough space on the stack

char sBody[30000];
[SM] Exception reported: Instruction contained invalid parameter

char[] sBody = new char[iBufferSize];
[SM] Exception reported: Not enough space on the heap

The plugin is a test plugin edited from somewhere else, so excuse the sloppy code. The issue is in the "TimePlayed_OnHTTPResponse" function, trying to declare a character string that has enough space for iBufferSize (which is around 28627 ).

char[] sBody = new char[iBufferSize];

PHP Code:

Add #pragma dynamic 20000 to increase the stacks space.
