+* _chkesp (MSVCRT.@)
+*
+* Trap to a debugger if the value of the stack pointer has changed.
+*
+* PARAMS
+* None.
+*
+* RETURNS
+* Does not return.
+*
+* NOTES
+* This function is available for iX86 only.
+*
+* When VC++ generates debug code, it stores the value of the stack pointer
+* before calling any external function, and checks the value following
+* the call. It then calls this function, which will trap if the values are
+* not the same. Usually this means that the prototype used to call
+* the function is incorrect. It can also mean that the .spec entry has
+* the wrong calling convention or parameters.
