Typedef Documentation

typedef struct GWEN_BUFFER GWEN_BUFFER

A dynamically resizeable text buffer.

Definition at line 41 of file buffer.h.

Function Documentation

GWENHYWFAR_API void GWEN_Buffer_AddMode	(	GWEN_BUFFER *	bf,
		uint32_t	mode
	)

Adds the give mode to the current mode of the buffer (such as GWEN_BUFFER_MODE_DYNAMIC).

Definition at line 195 of file buffer.c.

Referenced by GWEN_XMLContext_ReadFromString(), and GWEN_XMLNode_fromString().

Here is the caller graph for this function:

GWENHYWFAR_API int GWEN_Buffer_AdjustUsedBytes ( GWEN_BUFFER * bf )

The functions GWEN_Buffer_IncrementPos and GWEN_Buffer_DecrementPos only modify the internal position pointer. This function here adjusts the number of used bytes to just before the internal position pointer. This is often used to avoid copying, like in the following example:

char *p;
int i;
for (i=0; i<100; i++) {
  GWEN_Buffer_AllocRoom(buffer, 512);
  p=GWEN_Buffer_GetPosPtr(buffer);
  READ_512_BYTES_TO_P;
  GWEN_Buffer_IncrementPos(buffer, 512);
  GWEN_Buffer_AdjustUsedBytes(buffer);
}

Creates a new GWEN_BUFFER, which is a dynamically resizeable text buffer.

Parameters

buffer	If non-NULL, then this buffer will be used as actual storage space. Otherwise a new buffer will be allocated (with `size` bytes)
size	If `buffer` was non-NULL, then this argument must specifiy the size of that buffer. If `buffer` was NULL, then this argument specifies the number of bytes that will be allocated.
used	Number of bytes of the buffer actually used. This is interesting when reading from a buffer.
take_ownership	If `buffer` was non-NULL and this argument is nonzero, then the new GWEN_BUFFER object takes over the ownership of the given `buffer` so that it will be freed on GWEN_Buffer_free(). If this argument is zero, the given `buffer` will not be freed. If `buffer` was NULL, this argument has no effect.
