Hello Colleagues, I have not done C programming in years. I need some help in debugging a C program written by someone who has left our team. I have marked the lines having the error with "-->" Your kind assistance is very much appreciated. Here's the code: Code: 1 #include 2 #include 3 #include 4 static char *StdKey = "Transformation SaaS eNcRyPtIoN"; 5 static char *SourceStdDir = "./"; 6 static char *TargetStdDir = "/filer/"; 7 int 8 main(argc,argv) 9 int argc; 10 char **argv; 11 { 12 char *val; 13 char *buf; 14 int buflen = 2048; 15 int keylen; 16 char *SourceDir; 17 char *TargetDir; 18 char *InpFile; 19 char *OutFile; 20 int len; 21 int Inp; 22 int Out; 23 int In; 24 char *bufpos; 25 char *keypos; 26 int bufcnt; 27 int keycnt; 28 29 argc--; 30 argv++; 31 32 val = getenv("SourceDir"); 33 if(val == (char *)NULL) 34 { 35 SourceDir = SourceStdDir; 36 # ifdef debug 37 fprintf(stderr,"Using standard source directory %s\n,SourceDir); 38 # endif 39 } 40 else 41 { 42 len = strlen(val); 43 SourceDir = malloc((unsigned)(len + 1)); 44 if(SourceDir == (char **)NULL) 45 { 46 fprintf(stderr,"allocation error (SourceDir)!\n" ); 47 exit(1); 48 } 49 else 50 { 51 strcpy(SourceDir,val); 52 # ifdef debug 53 fprintf(stderr, 54 "Using environment SourceDir %s\n,Source Dir); 55 # endif 56 } 57 } 58 59 val = getenv("TargetDir"); 60 if(val == (char *)NULL) 61 { 62 TargetDir = TargetStdDir; 63 # ifdef debug 64 fprintf(stderr,"Using standard target directory %s\n,TargetDir); 65 # endif 66 } 67 else 68 { 69 len = strlen(val); 70 TargetDir = malloc((unsigned)(len + 1)); 71 if(TargetDir == (char **)NULL) 72 { 73 fprintf(stderr,"allocation error (TargetDir)!\n" ); 74 exit(1); 75 } 76 else 77 { 78 strcpy(TargetDir,val); 79 # ifdef debug 80 fprintf(stderr, 81 "Using environment target directory %s\n ,TargetDir); 82 # endif 83 } 84 } 85 86 val = getenv("EncryptionKey"); 87 if(val == (char *)NULL) 88 { 89 key = StdKey; 90 # ifdef debug 91 fprintf(stderr,"Using standard key %s\n,key); 92 # endif 93 } 94 else 95 { 96 len = strlen(val); 97 key = malloc((unsigned)(len + 1)); 98 if(key == (char **)NULL) 99 { 100 fprintf(stderr,"allocation error (key)!\n"); 101 exit(1); 102 } 103 else 104 { 105 strcpy(key,val); 106 # ifdef debug 107 fprintf(stderr, 108 "Using environment encryption key %s\n,k ey); 109 # endif 110 } 111 } 112 keylen = strlen(key); 113 114 buf = malloc((buflen)); 115 if(buf == (char **)NULL) 116 { 117 fprintf(stderr,"allocation error (buffer)!\n"); 118 exit(1); 119 } 120 121 while (argc--) 122 { 123 len = strlen(*argv) + strlen(SourceDir); 124 InpFile = malloc((unsigned)(len + 1)); 125 if(InpFile == (char **)NULL) 126 { 127 fprintf(stderr,"allocation error (InpFile)!\n"); 128 exit(1); 129 } 130 else 131 { 132 strcpy(InpFile,SourceDir); 133 strcat(InpFile,*argv); 134 # ifdef debug 135 fprintf(stderr, 136 "InpFile = %s\n,InpFile); 137 # endif 138 } 139 140 len = strlen(*argv) + strlen(TargetDir); 141 OutFile = malloc((unsigned)(len + 1)); 142 if(OutFile == (char **)NULL) 143 { 144 fprintf(stderr,"allocation error (OutFile)!\n"); 145 exit(1); 146 } 147 else 148 { 149 strcpy(OutFile,TargetDir); 150 strcat(OutFile,*argv); 151 # ifdef debug 152 fprintf(stderr, 153 "OutFile = %s\n,OutFile); 154 # endif 155 } 156 --> 157 Inp = open(InpFile;O_RDONLY); 158 if(Inp == -1) 159 { 160 fprintf(stderr,"file open error (InpFile)!\n"); 161 exit(1); 162 } 163 Out = open(OutFile,O_WRONLY | O_CREAT | O_TRUNC); 164 if(Out == -1) 165 { 166 fprintf(stderr,"file open error (OutFile)!\n"); 167 exit(1); 168 } 169 170 keycnt=0; 171 keypos=key; 172 fprintf(stdout, 173 "Processing InpFile = %s ",InpFile); 174 175 while (In = read(Inp,buf,buflen) > -1) 176 { 177 bufcnt=0; 178 bufpos=buf; 179 180 while (bufcnt < In) 181 { --> 182 bufpos++ ^= keypos++; 183 bufcnt++; 184 keycnt++; 185 if (keycnt = keylen) 186 { 187 keypos=key; 188 keycnt = 0; 189 } 190 } --> 191 if (write(Out,buf;In) < In) 192 { 193 fprintf(stderr,"file write error (OutFil e)!\n"); 194 exit(1); 195 } 196 fprintf(stdout, 197 "."); 198 } 199 200 close(Inp); 201 close(Out); 202 free(InpFile); 203 free(OutFile); 204 fprintf(stdout, 205 "Processing completed to OutFile = %s\n",OutFile ); 206 } 207 208 209 return(0); 210 } 211 Here are the error messages: pgpreplacement.c:157: error: expected â)â before â;â token pgpreplacement.c:157: error: too few arguments to function âopenâ pgpreplacement.c:182: error: invalid lvalue in assignment pgpreplacement.c:191: error: expected â)â before â;â token Yours truly, Regina
