can some one point me to a tsr utility/help/skeleton? Only C Gurus!

I want to write a program to periodically transmit a message. I have a program which already checks whether any thing is there in the outbox and if there is, it transmits the file.

I want to write a program which will automatically create and send a file to the destination at fixed time intervals.

Essentially, my transmission program looks for two files, one - the message file in the outbox and two - a schedule file containing the name and the length of the message file. The message file has a name which depends on the day and the month so that it can be identified. I have already written the code to do so.

My problem is how can i write a program (tsr) which will wait in the back-ground and fire the above program say once every 10 or fifteen minutes. Can any one help?

I work in TURBO-C on DOS only!

hey! before doin that u've to trap timer interrupt service routine and add ur tsr there. For TSRs u look in to the "Mastring MSDos by ray dunkan" and "Assemly language programmin by Peter able".

If you want to use TSR:s I suggest checking out this place:

http://cs.smith.edu/~thiebaut/ArtOfAssembly/artofasm.html

Especially chapter 18, that deals exclusively with TSR:s. The page is all assembly however, but since it's very easy to use inline assembly in Turbo C, and since you're exclusively using DOS I see no problem with using a bit of assembly =)

Hope it's of some use.
