Hi,
I have to write a Dump Tool for a file on UNIX. I have never written a dump tool before. Can anyone please guide me how to proceed??

Jump to Postyou will have to be a little more specific about the requirements -- a "Dump tool" can mean almost anything. My interpretation would be a program that displays the contents of database tables. Yours might be something else entirely.
Jump to PostI know there have been lots of those written -- google will show you a few, such as this one. It was written for dumping contents of RAM but you …

A dump program takes a file as argument, reads that file and gives a text dump of the file.

Hi,
The Dump Tool i wrote takes a binary file as an argument , reads it and gives a txt file as an output. But there is some problem with the code can anyone help me?
FILE *fp_inFile;
FILE *fp_outFile;
static int iGetABCFile(char*);
static int iGetXYZFile(char*);
char ctype; /* Two types of files can be passed as aruments file of type ABC or of type XYZ */
char caoutfile[512];
int main( int argc, char **argv ) {
/* Checking for correct number of arguments */
if((argc == NULL)||(argc > 3)) {
printf("\tErr -> command line\n");
printf("\tUSAGE : DumpFile Type Filename\n");
exit(NG);
}
else {
printf("\tCommand accepted -> Type :[%s] FileName :(%s)\n",argv[1],argv[2]);
}
/* Copying the inputfile name and concatinating ".txt" to the output file - If the inputfile is ABC then the output file should be ABC.txt*/
strcpy(caoutfile, argv[2]);
strcat(caoutfile,".txt");
printf("\tNew FileName = %s\n",caoutfile);
/* fopen */
if(NULL==(fp_inFile=fopen(argv[2],"rb"))) {
printf(“IN File Open Err! -> %s\n",argv[2]);
exit(NG);
}
if ((fp_outFile=fopen(caoutfile, "w")) == NULL) {
printf( "OutFile Open Error\n" );
exit( NG );

Some problem? Ok whats this iGetABCFile(char*)? You can't call functions like this
You have bunch of variables wich are not declared like:
ulNameRecordCount, usSubTypeCode, usSubTypeCode, usFeatureClassCode, aucAttributeType, ucFont.
You try to fprintf them to file but not readed from binary file.

This is wrong
fread((void *)ucLanguageCode, 1, 1, fp_inFile);
instead you should correct to
fread(&ucLanguageCode, 1, 1, fp_inFile);
So all (void *) in fread correct to &
