strtok

#include <stdlib.h>
char *strtok(char *str1, const char *str2);

Function strtok breaks a string (str1) into individual strings based on the so-called token. The string is separated by one delimiter (str2). “str2” may contain multiple tokens, e.g. str2 = “\ n” (ie separation in space, comma, New Line, Point).

    // this example shows how you can easy parse a csv file in c
    char csvcontent[] = "row;of a csv file; with cool content;parse csv in c";
    char seperator[] = ";";
    char *string;
    int i=1;
    string = strtok(csvcontent, seperator);
 
    while(string != NULL) {
          printf("column %d = %s\n", i++, string);
          string = strtok(NULL, seperator);
    }
return 0;
}

  column 1 = row
