1. trap 1. n. A program interrupt,
usually an interrupt caused by some exceptional situation in the user
program. In most cases, the OS performs some action, then returns control
to the program.
2. vi. To cause a trap.
“These instructionstrap to the monitor.” Also used
transitively to indicate the cause of the trap. “The monitor traps
all input/output instructions.”
This term is associated with assemblerprogramming (interrupt or exception is morecommon among
HLL programmers) and appears to be fading into
history among programmers as the role of assembler continues to shrink.
However, it is still important to computer architects and systems hackers
(see system, sense 1), who use it to distinguish
deterministically repeatable exceptions from timing-dependent ones (such as
I/O interrupts).
