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"

FUNCTION dlGetSymFromLib
DESCRIPTION
Handy function to get a pointer to a symbol from a library.
If libHandle is not null, it will be used as the handle to the library. In
that case libName wll not be used;
libHandle is an in / out parameter.
If libHandle is null, libName will be used to dlopen.
Either libHandle or libName must not be nullptr.
symName must not be null.
DEPENDENCIES
N/A
RETURN VALUE
pointer to symName. Could be nullptr if
Parameters are incorrect; or
libName can not be opened; or
symName can not be found.
