arrays - Parsing substrings from a string with "sscanf" function in C -

i have gps string below:

char gps_string[] = "$gprmc,080117.000,a,4055.1708,n,02918.9336,e,0.00,316.26,00,,,a*78"; 

i want parse substrings between commas below sequence:

$gprmc 080117.000 4055.1708 . . . 

i have tried sscanf function below:

 sscanf(gps_string,"%s,%s,%s,%s,%s,",char1,char2,char3,char4,char5); 

but not working. char1 array gets whole string if use above function.

actually have used strchr function in previous algorithm , got work it's easier , simplier if can work sscanf , parameters in substring.

by way, substrings between commas can vary. comma sequence fixed. example below gps string example not contain of parts because of sattellite problem:

char gps_string[] = "$gprmc,001041.799,v,,,,,0.00,0.00,060180,,,n*" 

there have been number of comments in other answers stating there number of problems strtok() , suggesting using strpbrk() instead. example of how used can found @ arrays , strpbrk in c

i not have compiler available not test this. have typos or other misteaks in code, sure can figure out meant.

in case use

char *string_buffer = gps_string; char *start = string_buffer; char *end; char *fields[maxfields]; int = 0; int n = 0; char *match = null;  while (end = strpbrk(start, ",")) // pointer next delimiter  {   /* found it, allocate enough space , nul */   /* if there ar 2 consecutive delimiters, nul gets entered */   n = end - start;   match = malloc(n + 1);    /* copy , nul terminate */   /* note if n 0, nothing copied not need test */   memcpy(match, start, n);   match[n] = '\0';    printf("found field entry: %s\n", match);   /* save actual match string pointer fields array*/   /* since match pointer in fields, not need freed */   fields[i++] = match;   start = end + 1; }  /* check last element in gps_string not ,    final field, has nul termination of string */   n = strlen(start);   match = malloc(n + 1);   /* note if n 0, terminator put in */   strcpy(match, start);   printf("found field entry: %s\n", match);   fields[i++] = match;   printf("total number of fields: %d\n", i);
