optionLoadLine(3)


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.
