CFG_SET_CONTEXT_FLAG(3) libcfg+ 0.6.2 CFG_SET_CONTEXT_FLAG(3)NAME
cfg_set_context_flag, cfg_clear_context_flag, cfg_get_context_flag,
cfg_set_context_flags, cfg_get_context_flags - libcfg+ context flags
manipulation functions
SYNOPSIS
The following functions can be used to set various context flags:
#include <cfg+.h>
void cfg_set_context_flag (const CFG_CONTEXT con, int flag);
void cfg_clear_context_flag (const CFG_CONTEXT con, int flag);
int cfg_get_context_flag (const CFG_CONTEXT con, int flag);
void cfg_set_context_flags (const CFG_CONTEXT con, int flags);
int cfg_get_context_flags (const CFG_CONTEXT con, int flags);
DESCRIPTION
You can set a context flag with cfg_set_context_flag(). You can clear
a flag with cfg_clear_context_flag(). To see whether a flag is set, use
cfg_get_context_flag(). It has a macro alias cfg_is_context_flag(),
which is identical in every way.
The functions cfg_set_context_flags() and cfg_get_context_flags() can
set and retrieve the value of all flags in one call.
A list of all settable context flags is provided in the following ta‐
ble.
"CONTEXT FLAGS"
CFG_IGNORE_MULTI
Ignore multiple arguments for a single option. The first argu‐
ment will be used to store the option value. The others are
skipped.
By default, multiple arguments for an option that has not
allowed them, cause the CFG_ERROR_MULTI error.
CFG_IGNORE_UNKNOWN
Ignore all unknown options.
The default behaviour is to produce the CFG_ERROR_UNKNOWN error
when an unknown option is encountered.
CFG_SKIP_FIRST
Setting this flag will cause the first argument on the command
line to be skipped. This flag affects only command line con‐
texts.
The default behaviour is to parse all command line arguments.
CFG_ADVANCED_LEFTOVERS
Advanced leftover arguments. Setting this flag will drop the
requirement of the leftover arguments to conform to the POSIX
standard.
The default behaviour is to require the leftover arguments to
conform to POSIX. According to POSIX, all option arguments must
precede any non-option (leftover) arguments. Once a non-option
argument is found, all remaining arguments are also interpreted
as non-option.
CFG_FILE_LINE_POS_USAGE
Setting this flag will cause the parsing of configuration file
to become line- instead of byte-oriented. This will also change
the meaning of the values stored in begin_pos and size.
By default, parsing is byte-oriented.
You can use the cfg_clear_context_flag() function to restore the value
of a flag to its default value.
