◆ buf_overflow()

int buf_overflow	(	const char *	buf1,
		const char *	buf2,
		size_t	bufsize
	)

We don't want to exceed the buffer size of buf1 by adding on buf2!

Parameters

buf1
buf2	buffers we plan on concatening. Can be NULL.
bufsize	size of buf1. Can be NULL.

Returns: true if overflow will occur.

◆ find_string()

sstring find_string ( const char * str )

Searches a string in the shared strings.

Parameters

str	string to search for.

Returns: pointer to identical string or NULL

Here is the caller graph for this function:

◆ free_string()

void free_string ( sstring str )

This will reduce the refcount, and if it has reached 0, str will be freed.

Parameters

str	string to release, which must have been returned from a previous add_string().

Note: the memory pointed to by str can be freed after this call, so don't use str anymore.
