Function Documentation

thwchar_t th_macthai2uni ( thchar_t  c  ) 

Convert character code from Mac Thai extended code to Unicode.

Parameters:
c : Mac Thai character/glyph to convert
Returns:
Corresponding Unicode code

thwchar_t th_tis2uni ( thchar_t  c  ) 

Convert character code from TIS-620 to Unicode.

Parameters:
c : TIS-620 character to convert
Returns:
Corresponding Unicode code

int th_tis2uni_line ( const thchar_t s,
thwchar_t result,
size_t  n 
)

Convert string from TIS-620 to Unicode.

Parameters:
s : source TIS-620 string (null-terminated)
result : buffer for storing resulting Unicode string
n : size of result buffer (as number of elements)
Returns:
the length of the output Unicode string

thchar_t th_uni2macthai ( thwchar_t  c  ) 

Convert character code from Unicode to Mac Thai extended code.

Parameters:
c : Unicode code to convert
Returns:
Corresponding Mac Thai extended code, or TH_ERR if conversion is impossible

thchar_t th_uni2tis ( thwchar_t  c  ) 

Convert character code from Unicode to TIS-620.

Parameters:
c : Unicode character to convert
Returns:
Corresponding TIS-620 code, or TH_ERR if conversion is impossible

int th_uni2tis_line ( const thwchar_t s,
thchar_t result,
size_t  n 
)

Parameters:
s : source Unicode string (null-terminated)
result : buffer for storing resulting TIS-620 string
n : size of result buffer (as number of elements)
Returns:
the length of the output TIS-620 string
Note that, since the conversion is lossy, some characters in the convesion result may be TH_ERR, indicating conversion error.
