Detailed Description

Function Documentation

svn_stringbuf_appendbyte()

void svn_stringbuf_appendbyte	(	svn_stringbuf_t *	targetstr,
		char	byte
	)

Append the single character byte onto targetstr.

This is an optimized version of svn_stringbuf_appendbytes() that is much faster to call and execute. Gains vary with the ABI. The advantages extend beyond the actual call because the reduced register pressure allows for more optimization within the caller.

Reallocs if necessary. targetstr is affected, nothing else is.

Since

New in 1.7.

svn_stringbuf_appendbytes()

void svn_stringbuf_appendbytes	(	svn_stringbuf_t *	targetstr,
		const char *	bytes,
		apr_size_t	count
	)

Append the array of bytes bytes of length count onto targetstr.

Reallocs if necessary. targetstr is affected, nothing else is.

Since

1.9 bytes can be NULL if count is zero.

svn_stringbuf_appendcstr()

void svn_stringbuf_appendcstr	(	svn_stringbuf_t *	targetstr,
		const char *	cstr
	)

Append the C string cstr onto targetstr.

Reallocs if necessary. targetstr is affected, nothing else is.

svn_stringbuf_appendfill()

void svn_stringbuf_appendfill	(	svn_stringbuf_t *	targetstr,
		char	byte,
		apr_size_t	count
	)

Append byte count times onto targetstr.

Reallocs if necessary. targetstr is affected, nothing else is.

Since

New in 1.9.

svn_stringbuf_appendstr()

void svn_stringbuf_appendstr	(	svn_stringbuf_t *	targetstr,
		const svn_stringbuf_t *	appendstr
	)

Append the stringbuf appendstr onto targetstr.

Reallocs if necessary. targetstr is affected, nothing else is.

svn_stringbuf_create_empty()

svn_stringbuf_t* svn_stringbuf_create_empty

(

apr_pool_t *

pool

)

Create a new, empty stringbuf.

Since

New in 1.8.

svn_stringbuf_create_ensure()

svn_stringbuf_t* svn_stringbuf_create_ensure	(	apr_size_t	minimum_size,
		apr_pool_t *	pool
	)

Create a new, empty stringbuf with at least minimum_size bytes of space available in the memory block.

The allocated string buffer will be at least one byte larger than minimum_size to account for a final '\0'.

Since

New in 1.6.

svn_stringbuf_create_wrap()

svn_stringbuf_t* svn_stringbuf_create_wrap	(	char *	str,
		apr_pool_t *	pool
	)

Create a new stringbuf using the given str as initial buffer.

Allocate the result in pool. In contrast to svn_stringbuf_create, the contents of str may change when the stringbuf gets modified.

Since

New in 1.9

svn_stringbuf_createv()

svn_stringbuf_t* svn_stringbuf_createv	(	apr_pool_t *	pool,
		const char *	fmt,
		va_list	ap
	)

Create a new stringbuf by printf-style formatting using fmt and ap.

This is the same as svn_stringbuf_createf() except for the different way of passing the variable arguments.

svn_stringbuf_ensure()

void svn_stringbuf_ensure	(	svn_stringbuf_t *	str,
		apr_size_t	minimum_size
	)

Make sure that str has at least minimum_size bytes of space available in the memory block.

The allocated string buffer will be at least one byte larger than minimum_size to account for a final '\0'.

Note

: Before Subversion 1.8 this function did not ensure space for one byte more than minimum_size. If compatibility with pre-1.8 behaviour is required callers must assume space for only minimum_size-1 data bytes plus a final '\0'.

svn_stringbuf_insert()

void svn_stringbuf_insert	(	svn_stringbuf_t *	str,
		apr_size_t	pos,
		const char *	bytes,
		apr_size_t	count
	)

Insert into str at position pos an array of bytes bytes which is count bytes long.

The resulting string will be count+str->len bytes long. If pos is larger than or equal to str->len, simply append bytes.

Reallocs if necessary. str is affected, nothing else is.

Note

The inserted string may be a sub-range of str.

Since

New in 1.8.

Since 1.9, bytes can be NULL if count is zero.

svn_stringbuf_leftchop()

void svn_stringbuf_leftchop	(	svn_stringbuf_t *	str,
		apr_size_t	nbytes
	)

Chop nbytes bytes off the start of str, but not more than str->len.

Since

New in 1.10.

svn_stringbuf_ncreate()

svn_stringbuf_t* svn_stringbuf_ncreate	(	const char *	bytes,
		apr_size_t	size,
		apr_pool_t *	pool
	)

Create a new stringbuf copied from the generic string of bytes, bytes, of length size bytes.

bytes is NOT assumed to be null-terminated, but the new stringbuf will be.

Since

Since 1.9, bytes can be NULL if size is zero.

svn_stringbuf_remove()

void svn_stringbuf_remove	(	svn_stringbuf_t *	str,
		apr_size_t	pos,
		apr_size_t	count
	)

Remove count bytes from str, starting at position pos.

If that range exceeds the current string data, truncate str at pos. If pos is larger than or equal to str->len, this will be a no-op. Otherwise, the resulting string will be str->len-count bytes long.

Since

New in 1.8.

svn_stringbuf_replace()

void svn_stringbuf_replace	(	svn_stringbuf_t *	str,
		apr_size_t	pos,
		apr_size_t	old_count,
		const char *	bytes,
		apr_size_t	new_count
	)

Replace in str the substring which starts at pos and is old_count bytes long with a new substring bytes which is new_count bytes long.

This is faster but functionally equivalent to the following sequence:

svn_stringbuf_remove(str, pos, old_count);
svn_stringbuf_insert(str, pos, bytes, new_count);

Since

New in 1.8.

Since 1.9, bytes can be NULL if new_count is zero.

svn_stringbuf_replace_all()

apr_size_t svn_stringbuf_replace_all	(	svn_stringbuf_t *	str,
		const char *	to_find,
		const char *	replacement
	)

Replace all occurrences of to_find in str with replacement.

Return the number of replacements made.

Since

New in 1.10.
