Function FindEndOfName

src/OpenColorIO/ParseUtils.cpp:702–747

Find the end of a name from a list contained in a string. The elements of the list are separated by the character defined by the sep argument. A name can be surrounded by quotes to enable names including the sep symbol, in other words, to prevent it from being used as a separator.
