Basic operations on data descriptions

Typedefs
typedef struct s_xbt_datadesc_type *	xbt_datadesc_type_t
	Opaque type describing a type description.

Functions
xbt_datadesc_type_t	xbt_datadesc_by_name (const char *name)
	Search a type description from its name.
xbt_datadesc_type_t	xbt_datadesc_by_name_or_null (const char *name)
	retrieve an existing message type from its name (or NULL if it does not exist).

Detailed Description

If you only want to send pre-existing types, simply retrieve the pre-defined description with the xbt_datadesc_by_name function. Existing types entail:

• char (both signed and unsigned)
• int (short, regular, long and long long, both signed and unsigned)
• float and double
• string (which is indeed a reference to a dynamically sized array of char, strlen being used to retrieve the size)

Example:

xbt_datadesc_type_t i = xbt_datadesc_by_name("int");
xbt_datadesc_type_t uc = xbt_datadesc_by_name("unsigned char");
xbt_datadesc_type_t str = xbt_datadesc_by_name("string");
