Message-ID: <9012141654.aa23943@WOLF.BRL.MIL> Date: 14 Dec 90 21:54:29 GMT Sender: usenet@ucbvax.BERKELEY.EDU Organization: The Internet Lines: 84 Can someone please explain why lint isn't happy with the following program? Am I really supposed to cast *loc to be "(signed char)*loc" which seems to be what is necessary? I thought that "signed char" was strictly an ANSI C construct. 1 >cat test.c #include main() { char *loc; char cp[64]; loc = "hello world"; (void)sprintf(cp, "%s=\"%c\"\n", "the first character", *loc); (void)printf("%s", cp); return(0); } 2 >lint test.c test.c ============== Warning: (10) sprintf: (char) format, (unsigned char) arg (arg 4) 3 >cc -o test test.c 4 >test the first character="h" For Those who want gritty details about environment: 4 >versions I = Installed, R = Removed Name Date Description I dev 90/09/14 4D1-3.3 Development System I dwb 89/11/20 DWB Opt PD, S4-DWB-3.2, 808-0012-010 I eoe1 90/09/14 4D1-3.3 Execution Only Environment (part 1) I eoe2 90/09/14 4D1-3.3 Execution Only Environment (part 2) I ftn 90/09/14 4D1-3.3 Fortran Option I maint1 (unknown product) I maint1 90/09/14 Maint1 Product 4D1-3.3.1 I nfs 90/09/14 4D1-3.3 Network File System I pfa 90/09/14 Power Fortran Accelerator R slip 90/02/09 IRIS Slip Product R vis 90/01/12 Personal Visualizer PD, 808-0160-001 I vtools 89/11/17 IRIS Visual Tools PD, 808-0167-001 5 >hinv 8 25 MHZ IP7 Processors FPU: MIPS R2010A/R3010 VLSI Floating Point Chip Revision: 2.0 CPU: MIPS R2000A/R3000 Processor Chip Revision: 2.0 Data cache size: 64 Kbytes Instruction cache size: 64 Kbytes Main memory size: 128 Mbytes Xylogics 1/2 inch tape controller 0 ctlr type: 772 firmware: 2.5 8 25 MHZ IP7 Processors FPU: MIPS R2010A/R3010 VLSI Floating Point Chip Revision: 2.0 CPU: MIPS R2000A/R3000 Processor Chip Revision: 2.0 Data cache size: 64 Kbytes Instruction cache size: 64 Kbytes Main memory size: 128 Mbytes Xylogics 1/2 inch tape controller 0 ctlr type: 772 firmware: 2.5 ENP-10 Ethernet controller 1, firmware version 4 (SGI) Integral Ethernet controller: Version 2 Xylogics 754 4-drive SMD disk controller 0: Firmware version 2.7.0 SMD Disk drive: unit 3 on Xylogics controller 0 SMD Disk drive: unit 2 on Xylogics controller 0 SMD Disk drive: unit 1 on Xylogics controller 0 SMD Disk drive: unit 0 on Xylogics controller 0 Xylogics 754 4-drive SMD disk controller 1: Firmware version 2.7.0 SMD Disk drive: unit 3 on Xylogics controller 1 SMD Disk drive: unit 2 on Xylogics controller 1 SMD Disk drive: unit 1 on Xylogics controller 1 SMD Disk drive: unit 0 on Xylogics controller 1 Integral SCSI controller 0: Version WD33C93 Disk drive: unit 1 on SCSI controller 0 Lee A.
