7.4.28.2 optionLoadLine

process a string for an option name and value

Usage:

optionLoadLine( pOpts, pzLine );

Where the arguments are:

	Name	Type	Description
	-----	-----	-------------
	pOpts	tOptions*	program options descriptor
	pzLine	const char*	NUL-terminated text

This is a user callable routine for setting options from, for example, the contents of a file that they read in. Only one option may appear in the text. It will be treated as a normal (non-preset) option.

When passed a pointer to the option struct and a string, it will find the option named by the first token on the string and set the option argument to the remainder of the string. The caller must NUL terminate the string. Any embedded new lines will be included in the option argument.

Invalid options are silently ignored. Invalid option arguments will cause a warning to print, but the function should return.
