Why is strtok causing a segmentation fault?
c, segmentation-fault, string
Solution
strtok modifies its first argument, hence it should be modifiable.
Maybe ReadName() returns a pointer to a read-only char array.Can you show us your ReadName() function.
If that is the reason for seg-faullt, you can create a copy of the char array before you pass it to strtok using the strdup function like:
char *copy = strdup(m);
token = strtok(copy,'-');
....
....
free(copy); // free the copy once you are done using it.
Problem
Why does the below code give Seg. Fault at last line? ``` char* m=ReadName(); printf("\nRead String %s\n",m); // Writes OK char* token; token=strtok(m,'-'); ``` As said, read string prints w/o problem, but why cannot split to tokens?
