optionLoadLine

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.
