I have a const char* variable which may have a value like "OpenStack:OpenStack1". I want to tokenize this const char* using strtok where the delimiter(which is of a const char* type) is ":" . But the problem is strtok is of following type: char * strtok ( char * str, const char * delimiters );
Which means I can't use const char* for the first input as it has to be char*. Could you say me how I can convert this const char* into char*?
Thank you.
Since strtok actually writes to your string, you need to make a writable copy of it to tokenize;
char* copy = strdup(myReadonlyString);
...tokenize copy...
free(copy);
Declare it as an array:
char tokenedStr[] = "OpenStack:OpenStack1";
if not possible, copy it to a char array.
You can make a copy of your non-modifiable string and then use strtok
.
You can portably use malloc
and strcpy
to copy the string.
