Macro Definition Documentation

◆ MAX

#define MAX	(		X,
			Y )

Value:

((X) > (Y) ? (X) : (Y))

◆ MIN

#define MIN	(		X,
			Y )

Value:

((X) > (Y) ? (Y) : (X))

Function Documentation

◆ DAFReader_cmp()

int DAFReader_cmp	(	const DAFReader *	lhs,
		const DAFReader *	rhs )

Compare two DAFReader objects.

If the "chr" fields differ, return positive if lhs->chr > rhs->chr; return negative if the reverse inequality holds. Otherwise return positive, 0, or negative to match the sign of lhs->nucpos - rhs->nucpos.

◆ DAFReader_next()

int DAFReader_next ( DAFReader * self )

Read the next site.

Returns: 0 on success; EOF on end of file; abort on other errors.

References iscomment(), strlowercase(), Tokenizer_print(), Tokenizer_printSummary(), Tokenizer_split(), Tokenizer_strip(), and Tokenizer_token().

◆ DAFReader_rewind()

int DAFReader_rewind ( DAFReader * self )

Rewind daf file.

Returns: 0 on success; -1 on failure
