caca_charset - libcaca character set conversions

Generated automatically by Doxygen for libcaca from the source code. libcaca Version 0.99.beta20 caca_charset(3caca)

These functions perform conversions between usual character sets.

__externuint32_tcaca_utf8_to_utf32(charconst*s,size_t*bytes) Convert a UTF-8 character read from a string and return its value in the UTF-32 character set. If the second argument is not null, the total number of read bytes is written in it. If a null byte was reached before the expected end of the UTF-8 sequence, this function returns zero and the number of read bytes is set to zero. This function never fails, but its behaviour with illegal UTF-8 sequences is undefined. Parameterss A string containing the UTF-8 character. bytes A pointer to a size_t to store the number of bytes in the character, or NULL. Returns The corresponding UTF-32 character, or zero if the character is incomplete. Referenced by caca_put_str(). __externsize_tcaca_utf32_to_utf8(char*buf,uint32_tch) Convert a UTF-32 character read from a string and write its value in the UTF-8 character set into the given buffer. This function never fails, but its behaviour with illegal UTF-32 characters is undefined. Parametersbuf A pointer to a character buffer where the UTF-8 sequence will be written. ch The UTF-32 character. Returns The number of bytes written. __externuint8_tcaca_utf32_to_cp437(uint32_tch) Convert a UTF-32 character read from a string and return its value in the CP437 character set, or '?' if the character has no equivalent. This function never fails. Parametersch The UTF-32 character. Returns The corresponding CP437 character, or '?' if not representable. __externuint32_tcaca_cp437_to_utf32(uint8_tch) Convert a CP437 character read from a string and return its value in the UTF-32 character set, or zero if the character is a CP437 control character. This function never fails. Parametersch The CP437 character. Returns The corresponding UTF-32 character, or zero if not representable. __externcharcaca_utf32_to_ascii(uint32_tch) Convert a UTF-32 character into an ASCII character. When no equivalent exists, a graphically close equivalent is sought. This function never fails, but its behaviour with illegal UTF-32 characters is undefined. Parametersch The UTF-32 character. Returns The corresponding ASCII character, or a graphically close equivalent if found, or '?' if not representable. __externintcaca_utf32_is_fullwidth(uint32_tch) Check whether the given UTF-32 character should be printed at twice the normal width (fullwidth characters). If the character is unknown or if its status cannot be decided, it is treated as a standard- width character. This function never fails. Parametersch The UTF-32 character. Returns 1 if the character is fullwidth, 0 otherwise. Referenced by caca_put_char(), and caca_put_str().
