NAME
optionLoadLine - process a string for an option name and value SYNOPSIS
#include <your-opts.h> cc [...] -o outfile infile.c -lopts [...] void optionLoadLine(tOptions* opts, char const* line); DESCRIPTION
This is a client program 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. The caller need not skip over any introductory hyphens. Any embedded new lines will be included in the option argument. If the input looks like one or more quoted strings, then the input will be "cooked". The "cooking" is identical to the string formation used in AutoGen definition files (@pxref{basic expression}), except that you may not use backquotes. opts program options descriptor line NUL-terminated text ERRORS
Invalid options are silently ignored. Invalid option arguments will cause a warning to print, but the function should return. SEE ALSO

NAME
optionFileLoad - Load the locatable config files, in order SYNOPSIS
#include <your-opts.h> cc [...] -o outfile infile.c -lopts [...] int optionFileLoad(tOptions* opts, char const* prog); DESCRIPTION
This function looks in all the specified directories for a configuration file ("rc" file or "ini" file) and processes any found twice. The first time through, they are processed in reverse order (last file first). At that time, only "immediate action" configurables are pro- cessed. For example, if the last named file specifies not processing any more configuration files, then no more configuration files will be processed. Such an option in the first named directory will have no effect. Once the immediate action configurables have been handled, then the directories are handled in normal, forward order. In that way, later config files can override the settings of earlier config files. See the AutoOpts documentation for a thorough discussion of the config file format. Configuration files not found or not decipherable are simply ignored. opts program options descriptor prog program name RETURN VALUE
0 -> SUCCESS, -1 -> FAILURE ERRORS
Returns the value, "-1" if the program options descriptor is out of date or indecipherable. Otherwise, the value "0" will always be returned. SEE ALSO
