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 * 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) op-
tion.
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.
