Data Structures
struct	ast_str
	The descriptor of a dynamic string XXX storage will be optimized later if needed We use the ts field to indicate the type of storage. Three special constants indicate malloc, alloca() or static variables, all other values indicate a struct ast_threadstorage pointer. More...

Function Documentation

int __ast_str_helper	(	struct ast_str **	buf,
		size_t	max_len,
		int	append,
		const char *	fmt,
		va_list	ap
	)

Core functionality of ast_str_(set|append)_va.

The arguments to this function are the same as those described for ast_str_set_va except for an addition argument, append. If append is non-zero, this will append to the current string instead of writing over it.

AST_DYNSTR_BUILD_RETRY is a legacy define. It should probably never again be used.

A return of AST_DYNSTR_BUILD_FAILED indicates a memory allocation error.

A return value greater than or equal to zero indicates the number of characters that have been written, not including the terminating ''. In the append case, this only includes the number of characters appended.

Note:

This function should never need to be called directly. It should through calling one of the other functions or macros defined in this file.

core handler for dynamic strings. This is not meant to be called directly, but rather through the various wrapper macros ast_str_set(...) ast_str_append(...) ast_str_set_va(...) ast_str_append_va(...)

int ast_build_string	(	char **	buffer,
		size_t *	space,
		const char *	fmt,
			...
	)

Build a string in a buffer, designed to be called repeatedly.

Note:

This method is not recommended. New code should use ast_str_*() instead.

This is a wrapper for snprintf, that properly handles the buffer pointer and buffer space available.

Parameters:

	buffer	current position in buffer to place string into (will be updated on return)
	space	remaining space in buffer (will be updated on return)
	fmt	printf-style format string

Return values:

	0	on success
	non-zero	on failure.

int ast_build_string_va	(	char **	buffer,

Build a string in a buffer, designed to be called repeatedly.

Returns:

Parameters:

	fmt	printf-style format string
	ap	varargs list of arguments for format

void ast_copy_string	(	char *	dst,
		const char *	src,
		size_t	size
	)			[inline]

Size-limited null-terminating string copy.

Parameters:

	dst	The destination buffer.
	src	The source string
	size	The size of the destination buffer

Returns:

Nothing.

This is similar to strncpy, with two important differences:

• the destination buffer will always be null-terminated
• the destination buffer is not filled with zeros past the copied string length These differences make it slightly more efficient, and safer to use since it will not leave the destination buffer unterminated. There is no need to pass an artificially reduced buffer size to this function (unlike strncpy), and the buffer does not need to be initialized to zeroes prior to calling this function.

Make sure something is false. Determine if a string containing a boolean value is "false". This function checks to see whether a string passed to it is an indication of an "false" value. It checks to see if the string is "no", "false", "n", "f", "off" or "0".

Return values:

	0	if val is a NULL pointer.
	-1	if "true".
	0	otherwise.

Compute a hash value on a string.

Parameters:

[in]	str	The string to add to the hash
[in]	hash	The hash value to add to

This version of the function is for when you need to compute a string hash of more than one string.

int ast_str_set	(	struct ast_str **	buf,
		size_t	max_len,

			...
	)			[inline]

Set a dynamic string using variable arguments.

Parameters:

	buf	This is the address of a pointer to a struct ast_str which should have been retrieved using ast_str_thread_get. It will need to be updated in the case that the buffer has to be reallocated to accomodate a longer string than what it currently has space for.
	max_len	This is the maximum length to allow the string buffer to grow to. If this is set to 0, then there is no maximum length. If set to -1, we are bound to the current maximum length.
	fmt	This is the format string (printf style)

Returns:

The return value of this function is the same as that of the printf family of functions.

Parameters:

struct ast_str * ast_str_thread_get	(	struct ast_threadstorage *	ts,

Retrieve a thread locally stored dynamic string.

Parameters:

	ts	This is a pointer to the thread storage structure declared by using the AST_THREADSTORAGE macro. If declared with AST_THREADSTORAGE(my_buf, my_buf_init), then this argument would be (&my_buf).

Returns:

This function will return the thread locally stored dynamic string associated with the thread storage management variable passed as the first argument. The result will be NULL in the case of a memory allocation error.

Example usage:

Strip leading/trailing whitespace and quotes from a string.

Parameters:

	s	The string to be stripped (will be modified).
	beg_quotes	The list of possible beginning quote characters.

Returns:

The stripped string.

This functions strips all leading and trailing whitespace characters from the input string, and returns a pointer to the resulting string. The string is modified in place.

It can also remove beginning and ending quote (or quote-like) characters, in matching pairs. If the first character of the string matches any character in beg_quotes, and the last character of the string is the matching character in end_quotes, then they are removed from the string.

Examples:

  ast_strip_quoted(buf, "[{(", "]})");

Make sure something is true. Determine if a string containing a boolean value is "true". This function checks to see whether a string passed to it is an indication of an "true" value. It checks to see if the string is "yes", "true", "y", "t", "on" or "1".

Return values:

	0	if val is a NULL pointer.
	-1	if "true".
	0	otherwise.
