Method ParseString

UTCP/src/utstrlst.cpp:139–219

ParseString Parses the given string into its components. A component is defined as the data found between the given separation characters in the sepChars string. Params string - string to parse sepChars - characters to use as the separations between each of the string components. index - the zero
