intr

interrupt the CPU

Synopsis:

#include <i86.h>
void intr( int inter_no, union REGPACK *regs );

Description:

The intr() function causes the computer's central processor (CPU) to be interrupted with an interrupt whose number is given by inter_no. Before the interrupt, the CPU registers are loaded from the structure located by regs.

All of the segment registers must contain valid values. Failure to do so will cause a segment violation when running in protect mode. If you don't care about a particular segment register, then it can be set to 0, which will not cause a segment violation. Following the interrupt, the structure located by regs is filled with the contents of the CPU registers.

This function is similar to the int86x() function, except that:

• only one structure is used for the register values
• the BP (EBP in 386 library) register is included in the set of registers that are passed and saved.
