_BreakPoint( ) API Library Routine Example
The following example uses the macro _BreakPoint( ) to place an INT 3 that debuggers recognize as a breakpoint.
SET LIBRARY TO BPOINT
#include <pro_ext.h>
FAR Example(ParamBlk FAR *parm)
{
int RetValue;
_BreakPoint(); // debugger breaks execution here
_HLock(parm->p[0].val.ev_handle);
_HLock(parm->p[1].val.ev_handle);
RetValue = _StrCmp(_HandToPtr(parm->p[0].val.ev_handle),
_HandToPtr(parm->p[1].val.ev_handle));
_RetInt(RetValue, 10); // does return control here
_HUnLock(parm->p[0].val.ev_handle);
_HUnLock(parm->p[1].val.ev_handle);
}
FoxInfo myFoxInfo[] = {
{"STRCMP", (FPFI) Example, 2, "C,C"},
};
FoxTable _FoxTable = {
(FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
