optionLoadLine(3)        Programmer's Manual       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* pOpts, char const* pzLine);


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.  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.

       pOpts  program options descriptor

       pzLine NUL-terminated text


ERRORS
       Invalid  options  are silently ignored.  Invalid option argu‐
       ments will cause a warning to print, but the function  should
       return.
