C String Manipulation

Like most people I too feel that perl string manipulation is much better than C. But recently I found this function called strsep(). It is the best possible function.
I am copying it below. Anyone and every1 who has ever parsed a file in C and found it difficult must read this.

char* strsep(char **stringp ,char *delim);
stringp is the initial string and delim is the delimiter character. The result is given as char* initial portion before the delimiter and rest is stored in stringp.

Eg. strcpy(string1,"shubham");
string2 = strsep(&string1,"u");

//Now string2 contains "sh" and string1 contains "bham"
