Function Documentation

str_endswith()

const char * str_endswith	(	const char *	str,
		const char *	suffix )

Checks case sensitive whether the string ends with a certain suffix.

Parameters

str	String to check.
suffix	Suffix to look for.

Returns

A pointer to the beginning of the suffix in the string str.

nullptr if the string suffix isn't a suffix of the string str.

Remarks

The strings are treated as null-terminated strings.

str_escape()

void str_escape	(	char **	dst,
		const char *	src,
		const char *	end )

Escapes \ and " characters in a string.

Parameters

dst	Destination array pointer, gets increased, will point to the terminating null.
src	Source array.
end	End of destination array.

str_in_list()

int str_in_list	(	const char *	list,
		const char *	delim,
		const char *	needle )

Checks if needle is in list delimited by delim.

Parameters

list	List.
delim	List delimiter.
needle	Item that is being looked for.

Returns

1 - Item is in list.

0 - Item isn't in list.

Remarks

The strings are treated as null-terminated strings.
