+FUNCTION loc_split_string
+
+DESCRIPTION:
+ This function is used to split a delimiter separated string into
+ sub-strings. This function does not allocate new memory to store the split
+ strings. Instead, it places '\0' in places of delimiters and assings the
+ starting address of the substring within the raw string as the string address
+ The input raw_string no longer remains to be a collection of sub-strings
+ after this function is executed.
+ Please make a copy of the input string before calling this function if
+ necessary
+
+PARAMETERS:
+ char *raw_string: is the original string with delimiter separated substrings
+ char **split_strings_ptr: is the arraw of pointers which will hold the addresses
+ of individual substrings
+ int max_num_substrings: is the maximum number of substrings that are expected
+ by the caller. The array of pointers in the above parameter
+ is usually this long
+ char delimiter: is the delimiter that separates the substrings. Examples: ' ', ';'
+
+DEPENDENCIES
+ N/A
+
+RETURN VALUE
+ int Number of split strings
+
+SIDE EFFECTS
+ The input raw_string no longer remains a delimiter separated single string.
+
+EXAMPLE
+ delimiter = ' ' //space
+ raw_string = "hello new user" //delimiter is space ' '
+ addresses = 0123456789abcd
+ split_strings_ptr[0] = &raw_string[0]; //split_strings_ptr[0] contains "hello"
+ split_strings_ptr[1] = &raw_string[6]; //split_strings_ptr[1] contains "new"
+ split_strings_ptr[2] = &raw_string[a]; //split_strings_ptr[2] contains "user"
+
