You even should not use 'c_str()', since 'strtok()' inserts null bytes where it encounters a separator, thus altering the string's buffer, which is not a good idea. Make a copy of the char buffer before you use 'strtok()', e.g.
#include <string>
#include <string.h>
//..
std::string str = "Just some text";
char* buf = strdup(str.c_str());
char* token = strtok(buf," ");
while (token) {
// ...
}
free(buf);
#include <string>
#include <string.h>
//..
std::string str = "Just some text";
char* buf = strdup(str.c_str());
char* token = strtok(buf," ");
while (token) {
// ...
}
free(buf);
Many thanks! :) Although one question, how come you're using string and string.h together? I thought .h was the older version (and obselete) compared with string?
No, not in this case. Even though you are right about e.g. 'iostream' and 'iostream.h', 'string.h' is a plain C header file that - among others - has e.g. 'strtok()', 'strdup()' and 'strstr()'. This file is not related to STL's 'string' header.
