Function Documentation

add_list_element()

char* add_list_element	(	char *	list,
		const char *	value
	)

Definition at line 412 of file strings.c.

crm_alpha_sort()

gint crm_alpha_sort	(	gconstpointer	a,
		gconstpointer	b
	)

Compare two strings alphabetically (case-insensitive)

Parameters

[in]	a	First string to compare
[in]	b	Second string to compare

Returns

0 if strings are equal, -1 if a < b, 1 if a > b

Note

Usable as a GCompareFunc with g_list_sort(). NULL is considered less than non-NULL.

crm_starts_with()

bool crm_starts_with	(	const char *	str,
		const char *	prefix
	)

Check whether a string starts with a certain sequence.

Parameters

[in]	str	String to check
[in]	match	Sequence to match against beginning of str

Returns

TRUE if str begins with match, FALSE otherwise

Note

This is equivalent to !strncmp(s, prefix, strlen(prefix)) but is likely less efficient when prefix is a string literal if the compiler optimizes away the strlen() at compile time, and more efficient otherwise.

Generate an operation key.

Parameters

Newly allocated memory containing operation key as string

Note

It is the caller's responsibility to free() the result.

Parameters

[in]

name

Actual system name to check

Returns

Non-NULL cluster message identifier corresponding to name

Note

The Pacemaker daemons were renamed in version 2.0.0, but the old names must continue to be used as the identifier for cluster messages, so that mixed-version clusters are possible during a rolling upgrade.
