Function Documentation

qpms_parse_doubles()

size_t qpms_parse_doubles	(	double **	target,
		size_t	start_index,
		const char *	orig
	)

Parse doubles from a string.

The doubles can be separated by whitespaces, comma or semicolon. The parsed numbers are saved into an array specified by *target that has been preallocated with malloc() to contain at least start_index members. If start_index is nonzero, the newly parsed numbers are saved to the positions starting from start_index.

If *target is NULL, the function allocates the necessary space.

Returns

Number of newly parsed doubles + start_index.

qpms_parse_doubles_fromfile()

size_t qpms_parse_doubles_fromfile	(	double **	target,
		size_t	start_index,
		const char *	filepath
	)

Parse doubles from a file.

The doubles can be separated by whitespaces, comma or semicolon. The parsed numbers are saved into an array specified by *target that has been preallocated with malloc() to contain at least start_index members. If start_index is nonzero, the newly parsed numbers are saved to the positions starting from start_index.

If *target is NULL, the function allocates the necessary space.

If filepath is NULL, "" or "-", read from stdin.

Returns

Number of newly parsed doubles + start_index.

qpms_parse_ndoubles()

size_t qpms_parse_ndoubles	(	double *	target,
		size_t	n,
		const char *	orig
	)

Parse a given number of doubles from a string.

The doubles can be separated by whitespaces, comma or semicolon.

Returns

If the string included up to n doubles, number of parsed doubles. If more, n+1.
