First let me say, please don't post code back all fixed. If you see where the error is, just tell me where it is and I will look to find it. Thanks, much appreciated!
/*
void processCmdLine(void)
Function: parses the command line using gettok(), and constructs an argument list.
Calls runCommand() when it reaches a semicolon or newline (created when
Enter key is pressed).
Pre-condition: inputBuff[] is not exmpty.
Post-condition: nil
Error-checking: Check for valid arguments being entered.
*/
void processCmdLine(void)
{
int j =(strlen(inputBuff) -1);
int i = 0;
fflush(stdout);
fflush(stdin);
while(i <= j){
if(i >= j){ break;}
if(inArgList(inputBuff[i]) == 1 && i < j)
{
char *temp = inputBuff[i];
int atemp = gettok(&temp);
printf("%c is %d \n",*temp, atemp);
while(inArgList(inputBuff[i]) == 1 && i != j)
{
if(i >= j){ break;}
i++;
}
}
if(i >= j){ break;}
if(inArgList(inputBuff[i]) == 0 && i <= j)
{
char *temp = inputBuff[i];
int atemp = gettok(&temp);
printf("%c is %d \n",*temp, atemp);
i++;
}
}
fflush(stdout);
fflush(stdin);
}the second function that is called within that is:
/*
int inArgList(char c)
Function: determines if a character can be part of an ordinary argument,
or a special character
*/
int inArgList(char c)
{
char *wrk;
for (wrk = special; *wrk; wrk++) {
if (c == *wrk)
return(0);
}
return(1);
}and the final fucntion is:
/*
int gettok(char **outptr)
Function: Separates the command line arguments into tokens.
Return value: Returns the token type.
*/
int gettok(char **outptr)
{
int type;
/* set the outptr string to tok */
*outptr = tok;
/* strip white space from the buffer containing the tokens */
while (*ptr == '\t' || *ptr == ' ')
ptr++;
*tok++ = *ptr;
/* set the variable depending on the token in the buffer */
switch (*ptr++) {
case '\n':
type = EOL;
break;
case '&':
type = AMPERSAND;
break;
case ';':
type = SEMICOLON;
break;
case '<':
type = INPUT_REDIRECT;
break;
case '>':
type = OUTPUT_REDIRECT;
break;
case '|':
type = PIPE;
break;
default:
type = ARG;
/* keep reading valid ordinary characters */
while (inArgList(*ptr))
*tok++ = *ptr++;
}
*tok++ = '\0';
return type;
}
