Function Documentation

void th_init_cell ( struct thcell_t cell  ) 

Initialize a Thai cell.

Parameters:
cell : pointer to the cell to initialize
Initializes values in the Thai cell struct.

size_t th_make_cells ( const thchar_t s,
size_t  len,
struct thcell_t  cells[],
size_t *  ncells,
int  is_decomp_am 
)

Tokenize string into cells.

Parameters:
s : the string
len : the length of string
cells : the array of output cells buffer
ncells : the address of integer storing the number of cells provided by the buffer, and to keep the number of resulting cells on return
is_decomp_am : whether SARA AM is to be decomposed into NIKHANIT and SARA AA and to be in separate cells
Returns:
total characters consumed
Tokenizes the string bounded by s and len into cells, and stores at most *ncells resulting cells in the cells buffer. On return, *ncells is also set to the total cells stored in cells[].

size_t th_next_cell ( const thchar_t s,
size_t  len,
struct thcell_t cell,
int  is_decomp_am 
)

Get first cell from string.

Parameters:
s : the string
len : the length of string
cell : the output buffer
is_decomp_am : whether SARA AM is to be decomposed into NIKHANIT and SARA AA and to be in separate cells
Returns:
total chars consumed by the cell
Gets first cell from the string bounded by s and len, and, if cell is not null, stores the cell data in it.

size_t th_prev_cell ( const thchar_t s,
size_t  pos,
struct thcell_t cell,
int  is_decomp_am 
)

Get previous cell from string.

Parameters:
s : the string
pos : the position in string to get cell previous to
cell : the output buffer
is_decomp_am : whether SARA AM is to be decomposed into NIKHANIT and SARA AA and to be in separate cells
Returns:
total chars consumed by the cell
Gets last cell from the string bounded by s and pos, and if cell is not null, stores the cell data in it.
