Date: Thu, 16 Dec 93 18:41 GMT From: mjo AT mrao DOT cam DOT ac DOT uk (Martin Oldfield) To: djgpp AT sun DOT soe DOT clarkson DOT edu Subject: Interrupt routines in 1.11 Are there any restrictions on length and the position of subroutines called by an interrupt and hooked in with a call to the wonderful _go32_dpmi_chain_protected_mode_interrupt_vector() subroutine ? We've got some code that works wonderfully well with a small interrupt handler but breaks when the handler grows or moves away from the _go32_....() call. I'm relatively sure that the handler doesn't call any taboo functions e.g. printf. Thanks in advance, M.
