I'm new to C language and want to explode a string like we do in PHP explode() function, I searched for a built-in function with the C standard library, and I found strtok , but It doesn't support empty tokens like 1,2,3,,5 . Inspired by the answers I found in this SO question I made this function, it is supposed to be thread safe and support empty tokens and doesn't change the original string
char* strTok(char** newString, char* delimiter)
char* string = *newString;
char* delimiterFound = (char*) 0;
int tokLenght = 0;
char* tok = (char*) 0;
if(!string) return (char*) 0;
delimiterFound = strstr(string, delimiter);
if(delimiterFound)
tokLenght = delimiterFound-string;
else
tokLenght = strlen(string);
tok = malloc(tokLenght + 1);
memcpy(tok, string, tokLenght);
tok[tokLenght] = '';
*newString = delimiterFound ? delimiterFound + strlen(delimiter) : (char*)0;
return tok;
I designed it to be used like
char* input = "1,2,3,4,5,6,7,,,10,";
char** inputP = &input;
char* tok;
while( (tok=strTok(inputP, ",")) )
printf("%sn", tok);
