VipsDbuf

Make sure dbuf has at least size bytes available after the write point.

since: 8.0

Destroy dbuf. This frees any allocated memory. Useful for dbufs on the stack.

since: 8.0

Return a pointer to an area you can write to, return length of area in size. Use vips_dbuf_allocate() before this call to set a minimum amount of space to have available.

since: 8.0

Initialize dbuf. You can also just init to zero, eg. VipsDbuf buf = {0};.

since: 8.0

Make sure dbuf is at least size bytes.

since: 8.0

Up to size bytes are read from the buffer and copied to data. The number of bytes transferred is returned.

since: 8.0

Reset the buffer to empty. No memory is freed, just the data size and write point are reset.

since: 8.0

Move the write point. whence can be SEEK_SET, SEEK_CUR, SEEK_END, with the usual meaning.

since: 8.0

Destroy a buffer, but rather than freeing memory, a pointer is returned. This must be freed with g_free().

since: 8.0

Return a pointer to dbuf‘s internal data.

since: 8.0

since: 8.0

Truncate the data so that it ends at the write point. No memory is freed.

since: 8.0

Append size bytes from data. dbuf expands if necessary.

since: 8.0

Write str to dbuf, but escape stuff that xml hates in text. Our argument string is utf-8.

since: 8.0

Format the string and write to dbuf.
