bionic (3) optionLoadLine.3.gz

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.
