void G__describe_option_rules | ( | void | ) |
Describe option rules (stderr)

void G__describe_option_rules_xml | ( | FILE * | fp | ) |
Describe option rules in XML format (internal use only)
fp | file where to print XML info |

int G__has_required_rule | ( | void | ) |
Checks if there is any rule RULE_REQUIRED (internal use only).
Definition at line 443 of file parser_dependencies.c.
References FALSE, RULE_REQUIRED, and TRUE.
void G_option_collective | ( | void * | first, |
... | |||
) |
Sets the options to be collective.
If any option is present, all the other options must also be present all or nothing from a set.
first | first given option |
Definition at line 347 of file parser_dependencies.c.
void G_option_excludes | ( | void * | first, |
... | |||
) |
Exclude selected options.
If the first option is present, none of the other options may also (should?) be present.
first | first given option |
Definition at line 320 of file parser_dependencies.c.
void G_option_exclusive | ( | void * | first, |
... | |||
) |
Sets the options to be mutually exclusive.
When running the module, at most one option from a set can be provided.
first | first given option |
Definition at line 202 of file parser_dependencies.c.
void G_option_required | ( | void * | first, |
... | |||
) |
Sets the options to be required.
At least one option from a set must be given.
first | first given option |
Definition at line 226 of file parser_dependencies.c.
void G_option_requires | ( | void * | first, |
... | |||
) |
Define a list of options from which at least one option is required if first option is present.
If the first option is present, at least one of the other options must also be present.
If you want all options to be provided use G_option_requires_all() function. If you want more than one option to be present but not all, call this function multiple times.
first | first given option |
Definition at line 257 of file parser_dependencies.c.
void G_option_requires_all | ( | void * | first, |
... | |||
) |
Define additionally required options for an option.
If the first option is present, all the other options must also be present.
If it is enough if only one option from a set is present, use G_option_requires() function.
first | first given option |
Definition at line 293 of file parser_dependencies.c.
void G_option_rule | ( | int | type, |
int | nopts, | ||
void ** | opts | ||
) |
Set generic option rule.
Supported rule types:
type | rule type |
nopts | number of options in the array |
opts | array of options |
