◆ ast_cli_allow_at_shutdown()

int ast_cli_allow_at_shutdown ( struct ast_cli_entry * e )

Allow a CLI command to be executed while Asterisk is shutting down.

CLI commands by defeault are disabled when Asterisk is shutting down. This is to ensure the safety of the shutdown since CLI commands may attempt to access resources that have been freed as a result of the shutdown.

If a CLI command should be allowed at shutdown, then the best way to enable this is to call ast_cli_allow_at_shutdown during the CLI_INIT state of the CLI handler.

◆ ast_cli_completion_add()

int ast_cli_completion_add ( char * value )

Add a result to a request for completion options.

Parameters

value A completion option text.

Return values

0	Success
-1	Failure

This is an alternative to returning individual values from CLI_GENERATE. Instead of repeatedly being asked for the next match and having to start over, you can call this function repeatedly from your own stateful loop. When all matches have been added you can return NULL from the CLI_GENERATE function.

Note: This function always eventually results in calling ast_free on value.

◆ ast_cli_completion_matches()

char ** ast_cli_completion_matches	(	const char *	text,

	)

Generates a NULL-terminated array of strings that 1) begin with the string in the second parameter, and 2) are valid in a command after the string in the first parameter.

The first entry (offset 0) of the result is the longest common substring in the results, useful to extend the string that has been completed. Subsequent entries are all possible values, followed by a NULL. All strings and the array itself are malloc'ed and must be freed by the caller.

Warning: This function cannot be called recursively so it will always fail if called from a CLI_GENERATE callback.

◆ ast_cli_completion_vector()

struct ast_vector_string * ast_cli_completion_vector	(	const char *	text,

	)

Generates a vector of strings for CLI completion.

Parameters

text	Complete input being matched.
word	Current word being matched

The results contain strings that both: 1) Begin with the string in word. 2) Are valid in a command after the string in text.

The first entry (offset 0) of the result is the longest common substring in the results, useful to extend the string that has been completed. Subsequent entries are all possible values.

Note: All strings and the vector itself are malloc'ed and must be freed by the caller.; The vector is sorted and does not contain any duplicates.

Warning: This function cannot be called recursively so it will always fail if called from a CLI_GENERATE callback.
