re[2]: [suse-programming-e] CD burning API

Thanks That does sound perfect!!!! It says it requires a kernel patch. SInce SuSE sponsors a mailing list, I assume the SUSE kernels include the patch. I've just signed up for the mailing list.

re[2]: [suse-programming-e] CD burning API

Anders, I'm sorry to hear there is not a standard API for CD writers, but I can live with that. We will just standardize on one model. As to using scripts, this is between an inhouse project and a full product. We do a lot contract work for a major car manufacturer, and they have asked us to put together a proposed solution that allows every car to photographed at the start and end of being transported. i.e. Take a series of pictures before it goes on a train, and a series when it comes off. The idea is that if a car arrives at a dealership with damage, we can use the photos to isolate when the damage occured and get the appropriate party to pay for fixing it. We would end up with 100 or so dedicated computers spread around the transportation system. We want the process to be extremely automated. i.e. We might setup designated photo areas. Then have each car driven into this area. Use a sensor to know when the car arrives and have several prepositioned cameras take one picture each. Then once a week or so, have the CD removed and mailed in for archiving. We are at the brainstorming stage in this project, so we really don't know what we going to do.

CD burning API
by Greg Freemyer 31 May '02

31 May '02

Guys, I'm new to this list, but I believe the below is appropriate. I've just been asked if it is feasible to have a custom program the fires off when a USB camera is docked, reads in all the images and writes them to CD. Then repeat the process the next day, but this time we append to the CD. Finally once a month or so the CD, is removed and mailed off. This sounds relatively easy, but I don't know for sure I know jphoto has the camera interface logic that I need. Where can I find a CD-burner API that allows me to leave the session open. Is there a limited number of burning sessions allowed, or just until the disk fills up. FYI: I don't know what language we will do this in. We have C/C++/Java skills inhouse, so likely one of those, but I'm also interested in trying that Delphi Linux product.

It uses a simple table lookup to convert an entire buffer. We also have a swedish to ebcdic as well. static unsigned char const latin1_to_ebcdicus[256] = { 0, 1, 2, 3, 4, 5, 6, 7, /* 0 - 7 */ 8, 9, 10, 11, 12, 13, 14, 15, /* 8 - 15 */ 16, 17, 18, 19, 20, 21, 22, 23, /* 16 - 23 */ 24, 25, 26, 27, 28, 29, 30, 31, /* 24 - 31 */ 64, 90, 127, 123, 91, 108, 80, 125, /* 32 - 39 */ 77, 93, 92, 78, 107, 96, 75, 97, /* 40 - 47 */ 240, 241, 242, 243, 244, 245, 246, 247, /* 48 - 55 */ 248, 249, 122, 94, 76, 126, 110, 111, /* 56 - 63 */ 124, 193, 194, 195, 196, 197, 198, 199, /* 64 - 71 */ 200, 201, 209, 210, 211, 212, 213, 214, /* 72 - 79 */ 215, 216, 217, 226, 227, 228, 229, 230, /* 80 - 87 */ 231, 232, 233, 36, 224, 41, 59, 109, /* 88 - 95 */ 121, 129, 130, 131, 132, 133, 134, 135, /* 96 - 103 */ 136, 137, 145, 146, 147, 148, 149, 150, /* 104 - 111 */ 151, 152, 153, 162, 163, 164, 165, 166, /* 112 - 119 */ 167, 168, 169, 192, 79, 208, 161, 255, /* 120 - 127 */ 128, 47, 98, 99, 100, 101, 102, 103, /* 128 - 135 */ 104, 105, 138, 139, 140, 141, 142, 143, /* 136 - 143 */ 144, 119, 44, 37, 172, 62, 63, 112, /* 144 - 151 */ 113, 114, 154, 155, 156, 157, 158, 159, /* 152 - 159 */ 160, 61, 74, 116, 117, 118, 106, 120, /* 160 - 167 */ 45, 58, 170, 171, 95, 173, 174, 175, /* 168 - 175 */ 176, 177, 178, 179, 180, 181, 182, 183, /* 176 - 183 */ 184, 185, 186, 187, 188, 189, 190, 191, /* 184 - 191 */ 35, 65, 66, 67, 68, 69, 70, 71, /* 192 - 199 */ 72, 73, 202, 203, 204, 205, 206, 207, /* 200 - 207 */ 39, 115, 46, 60, 40, 43, 32, 38, /* 208 - 215 */ 81, 82, 218, 219, 220, 221, 222, 223, /* 216 - 223 */ 42, 225, 83, 84, 85, 86, 87, 88, /* 224 - 231 */ 89, 33, 234, 235, 236, 237, 238, 239, /* 232 - 239 */ 48, 49, 50, 51, 52, 53, 54, 55, /* 240 - 247 */ 56, 57, 250, 251, 252, 253, 254, 34, /* 248 - 255 */ }; void us_ascii_to_ebcdic ( void *in, void *out, int len ) { unsigned char *src = (unsigned char *) in, *dst = (unsigned char *) out; for (; lgt > 0; lgt--) *dst++ = latin1_to_ebcdicus[(int) *src++]; }
