#define UTIL_API   /* nothing */

hide the symbols this header declares by default

The expectation is that users of this header (applications, shared libraries, or static libraries) want to call gv_base64 but not re-export it to their users. This annotation is only correct while the containing library is built statically. If it were built as a shared library, gv_base64 would need to have default visibility (and thus be unavoidably re-exported) in order to be callable.

Function Documentation

gv_base64()

UTIL_API char * gv_base64	(	const unsigned char *	source,
		size_t	size
	)

Base64 encode some data

This function does not return on failure, like memory allocation. It calls exit. The caller is expected to free the returned pointer.

Parameters

source	Pointer to the start of data to encode
size	Number of bytes in the source

Returns

A buffer of the encoded data
