How to Return an array of strings in C (char**)

[vignesh4u]

I am trying to implement the Split function in C ie.
if i have a string: char* S="This is a test";
and if i try to split based on space ' ' it should return an array of
strings like:

{"This","is","a ","test"} .

I tried to implement it as given below but am getting a segmentation
fault. I would really appreciate if some one could give me an answer
on this issue:

char** split(char str[],int*c) {
int start=0;
int end =0 ;
char** temp=NULL;
char** ptr;
int count=0;
int length = strlen(str);
//first counting the number of spaces
// to know the number of elements in the array
while (str) {
if (*str==' ') count++;
}
printf("count value is %d \n",count);
// I am doubt ful about the malloc too
ptr = (char**) malloc(sizeof(c har)*(count+1)) ;
*c = count+1;

while(end<lengt h) {
ptr = str + start;
if (str[end]!=' ' || length) {
end++;
}
if (str[end]!='\0') {// replacing spaces with \0
str[end]='\0';
}
if (!temp) temp= ptr;
ptr++;
}
return temp;
}

Thanks

The only one it finds is this one I'm replying to.

That should be toksplit.c
