I would like to know what I am doing wrong. I am keeping a history of commands and want to save argbuf each time I have used it into another array.<br />
My code is like this:<br />
<br />
char *argbuf[ARG_MAX+1]; &nbsp;<br />
char **history[ARG_MAX+1];<br />
&nbsp; &nbsp; <br />
if (his_count &lt;&nbsp;HIS_MAX) {<br />
&nbsp; &nbsp; strcpy(*history[his_count]<wbr />, *argbuf); &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;// Add the command to history<br />
&nbsp; &nbsp; his_count++; }<br />
else { &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Update history<br />
&nbsp; &nbsp; i = 0;<br />
&nbsp; &nbsp; while (i &lt;&nbsp;(HIS_MAX-1)) {<br />
&nbsp; &nbsp; &nbsp; &nbsp; strcpy(*history[i], *history[i+1]);<br />
&nbsp; &nbsp; &nbsp; &nbsp; i++; }<br />
&nbsp; &nbsp; &nbsp;strcpy(*history[i], *argbuf); }<br />
<br />
I get a segmentation fault, what am I doing wrong? <br />
Thanks

else {                                           // Update history
    i = 0;
    while (i < (HIS_MAX-1)) {
        strcpy(*history[i], *history[i+1]);
        i++; }
     strcpy(*history[i], *argbuf); }

copying an array of pointers into an multidimensional array

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
