C string functions

Functions
apr_array_header_t *	svn_cstring_split (const char *input, const char *sep_chars, svn_boolean_t chop_whitespace, apr_pool_t *pool)
	Divide input into substrings along sep_chars boundaries, return an array of copies of those substrings (plain const char*), allocating both the array and the copies in pool.
void	svn_cstring_split_append (apr_array_header_t *array, const char *input, const char *sep_chars, svn_boolean_t chop_whitespace, apr_pool_t *pool)
	Like svn_cstring_split(), but append to existing array instead of creating a new one.
svn_boolean_t	svn_cstring_match_glob_list (const char *str, const apr_array_header_t *list)
	Return TRUE iff str matches any of the elements of list, a list of zero or more glob patterns.
svn_boolean_t	svn_cstring_match_list (const char *str, const apr_array_header_t *list)
	Return TRUE iff str exactly matches any of the elements of list.
int	svn_cstring_count_newlines (const char *msg)
	Return the number of line breaks in msg, allowing any kind of newline termination (CR, LF, CRLF, or LFCR), even inconsistent.
char *	svn_cstring_join (const apr_array_header_t *strings, const char *separator, apr_pool_t *pool)
	Return a cstring which is the concatenation of strings (an array of char *) each followed by separator (that is, separator will also end the resulting string).
int	svn_cstring_casecmp (const char *str1, const char *str2)
	Compare two strings atr1 and atr2, treating case-equivalent unaccented Latin (ASCII subset) letters as equal.
svn_error_t *	svn_cstring_strtoi64 (apr_int64_t *n, const char *str, apr_int64_t minval, apr_int64_t maxval, int base)

svn_error_t* svn_cstring_atoi	(	int *	n,
		const char *	str
	)

Parse the C string str into a 32 bit number, and return it in *n.

Assume that the number is represented in base 10. Raise an error if conversion fails (e.g. due to overflow).

Since:

New in 1.7.

svn_error_t* svn_cstring_atoi64	(	apr_int64_t *	n,
		const char *	str
	)

Parse the C string str into a 64 bit number, and return it in *n.

Assume that the number is represented in base 10. Raise an error if conversion fails (e.g. due to overflow).

Since:

New in 1.7.

svn_error_t* svn_cstring_atoui	(	unsigned int *	n,
		const char *	str
	)

Parse the C string str into an unsigned 32 bit number, and return it in *n.

Assume that the number is represented in base 10. Raise an error if conversion fails (e.g. due to overflow).

Since:

New in 1.7.

svn_error_t* svn_cstring_atoui64	(	apr_uint64_t *	n,
		const char *	str
	)

Parse the C string str into an unsigned 64 bit number, and return it in *n.

Assume that the number is represented in base 10. Raise an error if conversion fails (e.g. due to overflow).

Since:

New in 1.7.

int svn_cstring_casecmp	(	const char *	str1,
		const char *	str2
	)

Compare two strings atr1 and atr2, treating case-equivalent unaccented Latin (ASCII subset) letters as equal.

Returns in integer greater than, equal to, or less than 0, according to whether str1 is considered greater than, equal to, or less than str2.

Since:

New in 1.5.

int svn_cstring_count_newlines

(

const char *

msg

)

Return the number of line breaks in msg, allowing any kind of newline termination (CR, LF, CRLF, or LFCR), even inconsistent.

Since:

New in 1.2.

char* svn_cstring_join	(	const apr_array_header_t *	strings,
		const char *	separator,
		apr_pool_t *	pool
	)

Return a cstring which is the concatenation of strings (an array of char *) each followed by separator (that is, separator will also end the resulting string).

Allocate the result in pool. If strings is empty, then return the empty string.

Since:

New in 1.2.

svn_boolean_t svn_cstring_match_list	(	const char *	str,
		const apr_array_header_t *	list
	)

Return TRUE iff str exactly matches any of the elements of list.

Since:

new in 1.7

apr_array_header_t* svn_cstring_split	(	const char *	input,
		const char *	sep_chars,
		svn_boolean_t	chop_whitespace,
		apr_pool_t *	pool
	)

Divide input into substrings along sep_chars boundaries, return an array of copies of those substrings (plain const char*), allocating both the array and the copies in pool.

None of the elements added to the array contain any of the characters in sep_chars, and none of the new elements are empty (thus, it is possible that the returned array will have length zero).

If chop_whitespace is TRUE, then remove leading and trailing whitespace from the returned strings.

void svn_cstring_split_append	(	apr_array_header_t *	array,
		const char *	input,
		const char *	sep_chars,
		svn_boolean_t	chop_whitespace,
		apr_pool_t *	pool
	)

Like svn_cstring_split(), but append to existing array instead of creating a new one.

Allocate the copied substrings in pool (i.e., caller decides whether or not to pass array->pool as pool).

svn_error_t* svn_cstring_strtoi64	(	apr_int64_t *	n,
		const char *	str,
		apr_int64_t	minval,
		apr_int64_t	maxval,
		int	base
	)

Parse the C string str into a 64 bit number, and return it in *n.

Assume that the number is represented in base base. Raise an error if conversion fails (e.g. due to overflow), or if the converted number is smaller than minval or larger than maxval.

Since:

New in 1.7.

svn_error_t* svn_cstring_strtoui64	(	apr_uint64_t *	n,
		const char *	str,
		apr_uint64_t	minval,
		apr_uint64_t	maxval,
		int	base
	)

Parse the C string str into an unsigned 64 bit number, and return it in *n.

Assume that the number is represented in base base. Raise an error if conversion fails (e.g. due to overflow), or if the converted number is smaller than minval or larger than maxval.
