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" |
