NAME¶
optionLoadLine - process a string for an option name and value
SYNOPSIS¶
#include <
your-opts.h>
cc [...] -o outfile infile.c -l
opts [...]
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 arguments will cause a
warning to print, but the function should return.
