    <p>I am working on TTCN-3 (Testing and Test Control Notation) scripting language. I wanted to prepare on guideline checker for this code files. <p>For that I want to read lines of TTCN-3 script file( some thing like file.ttcn ) one by one into a buffer. But for me fopen / sopen / open / fgetc / fscanf are not able to work properly and are not reading the file correctly. It is giving NULL. Is there any way I can read characters of it into a buffer. I think C cannot read files with more than three extension characters (like .ttcn). Forgive me if my assumption is wrong.</p> <p>My Environment is Turbo C on windows. <p><strong>Edit</strong>: <p>Yes I checked those errors also but they are giving unknown error for read() and no such file or directory exists. <p>My code is as follows <p> </p> <pre><code>#include &lt;errno.h&gt; #include &lt;io.h&gt; #include &lt;fcntl.h&gt; #include &lt;sys\stat.h&gt; #include &lt;process.h&gt; #include &lt;share.h&gt; #include &lt;stdio.h&gt; int main(void) { int handle; int status; int i=0; char ch; FILE *fp; char *buffer; char *buf; clrscr(); handle = sopen("c:\\tc\\bin\\hi.ttcn", O_BINARY, SH_DENYNONE, S_IREAD); </code></pre> <p>/<em>here even I used O_TEXT and others</em>/</p> <pre><code> if (!handle) { printf("sopen failed\n"); // exit(1); } printf("\nObtained string %s @",buf); close(handle); fp=fopen("c:\\tc\\bin\\hi.ttcn","r"); \\sorry for the old version of one slash if(fp==NULL) \\I was doing it with argv[1] for opening { \\user given file name printf("\nCannot open file"); } ch=fgetc(fp); i=0; while(i&lt;10) { printf("\ncharacter is %c %d",ch,ch); i++; //Here I wanted to take characters into ch=fgetc(fp); //buffer } getch(); return 0; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
