The maximum length value in CX specifies the number of characters which could be copied into the target string. You have to
allocate one more character for the null termination.
Example (tested with Borland C/C++ 5.02):
int iniGetString(char *sectionName, char *itemName, char *target, int maxlen)
{
union REGS inregs;
union REGS outregs;
struct SREGS sregs;
inregs.h.ah = 0x24;
inregs.x.bx = FP_SEG(sectionName);
inregs.x.si = FP_OFF(sectionName);
sregs.es = FP_SEG(itemName);
inregs.x.di = FP_OFF(itemName);
inregs.x.cx = maxlen;
sregs.ds = FP_SEG(target);
inregs.x.dx = FP_OFF(target);
int86x(0xA0,&inregs,&outregs,&sregs);
return outregs.x.ax;
}
// Declare a target buffer to be filled by iniGetString().
unsigned char target[101];
iniGetString("MY_SECTION", "MY_ITEM", target, 100);
// Now target contains the chip.ini text for this item
