decode_pure()

static const char* PLMD::h36::decode_pure ( const int *  digits_values, unsigned  digits_size, const char *  s, unsigned  s_size, int *  result  )

static

digits_lower()

C port of the hy36encode() and hy36decode() functions in the hybrid_36.py Python prototype/reference implementation. See the Python script for more information.

This file has no external dependencies, NOT even standard C headers. Optionally, use hybrid_36_c.h, or simply copy the declarations into your code.

encode_pure()

static void PLMD::h36::encode_pure ( const char *  digits, unsigned  digits_size, unsigned  width, int  value, char *  result  )

static

fill_with_stars()

static void PLMD::h36::fill_with_stars ( unsigned  width, char *  result  )

static

hy36decode()

const char * PLMD::h36::hy36decode	(	unsigned	width,
		const char *	s,
		unsigned	s_size,
		int *	result
	)

hybrid-36 decoder: converts string s to integer result

width: must be 4 (e.g. for residue sequence numbers) or 5 (e.g. for atom serial numbers)

s: string to be converted does not have to be null-terminated

s_size: size of s must be equal to width, or an error message is returned otherwise

result: integer holding the conversion result

return value: pointer to error message, if any, or 0 on success

Example usage (from C++): int result; const char* errmsg = hy36decode(width, "A1T5", 4, &result); if (errmsg) throw std::runtime_error(errmsg);

hy36encode()

const char * PLMD::h36::hy36encode	(	unsigned	width,
		int	value,
		char *	result
	)

hybrid-36 encoder: converts integer value to string result

width: must be 4 (e.g. for residue sequence numbers) or 5 (e.g. for atom serial numbers)

value: integer value to be converted

result: pointer to char array of size width+1 or greater on return result is null-terminated

return value: pointer to error message, if any, or 0 on success

Example usage (from C++): char result[4+1]; const char* errmsg = hy36encode(4, 12345, result); if (errmsg) throw std::runtime_error(errmsg);

invalid_number_literal()

static const char* PLMD::h36::invalid_number_literal ( )

static

unsupported_width()

static const char* PLMD::h36::unsupported_width ( )

static

value_out_of_range()

static const char* PLMD::h36::value_out_of_range ( )
