int alpha_char_strlen

(

const AlphaChar *

str

)

Alphabet string length.

Parameters:

str

: the array of null-terminated AlphaChar string to measure

Returns:

the total characters in str.

int alpha_map_add_range	(	AlphaMap *	alpha_map,
		AlphaChar	begin,
		AlphaChar	end
	)

Add a range to alphabet map.

Parameters:

	alpha_map	: the alphabet map object
	begin	: the first character of the range
	end	: the last character of the range

Add a range of character codes from begin to end to the alphabet set.

AlphaMap* alpha_map_clone

(

const AlphaMap *

a_map

)

Create a clone of alphabet map.

Parameters:

a_map

: the source alphabet map to clone

Returns:

a pointer to the alphabet map clone, NULL on failure

The created object must be freed with alpha_map_free().

void alpha_map_free

(

AlphaMap *

alpha_map

)

Free an alphabet map object.

Parameters:

alpha_map

: the alphabet map object to free

Destruct the alpha_map and free its allocated memory.

AlphaMap* alpha_map_new

(

)

Create new alphabet map.

Returns:

a pointer to the newly created alphabet map, NULL on failure

Create a new empty alphabet map. The map contents can then be added with alpha_map_add_range().

The created object must be freed with alpha_map_free().
