Check if a string is all numbers and whitespace.

Documentation

Check if a string is all numbers and whitespace. Any regular alphabetic symbols or punctuation encountered invalidate the string as a numeric string. This can be used to check a multiple-value string. The string must be NULL-terminated, or the call never ends.
Parameters:
text - A string to check.
Returns:
TRUE if the string only contains whitespace and numbers.
