Typedef Documentation

◆ Varinfo

typedef const _Varinfo * wreport::Varinfo

Varinfo reference.

Since the actual structures are allocated inside the Vartable objects and never deallocated until the program quits, we do not need to track memory allocation and we can just refer to variable information with const pointers.

Enumeration Type Documentation

◆ ErrorCode

enum wreport::ErrorCode

C-style error codes used by exceptions.

Enumerator
WR_ERR_NONE	No error.
WR_ERR_NOTFOUND	Item not found.
WR_ERR_TYPE	Wrong variable type.
WR_ERR_ALLOC	Cannot allocate memory.
WR_ERR_ODBC	ODBC error.
WR_ERR_HANDLES	Handle management error.
WR_ERR_TOOLONG	Buffer is too short to fit data.
WR_ERR_SYSTEM	Error reported by the system.
WR_ERR_CONSISTENCY	Consistency check failed.
WR_ERR_PARSE	Parse error.
WR_ERR_WRITE	Write error.
WR_ERR_REGEX	Regular expression error.
WR_ERR_UNIMPLEMENTED	Feature not implemented.
WR_ERR_DOMAIN	Value outside acceptable domain.

Function Documentation

◆ convert_units()

double wreport::convert_units	(	const char *	from,
		const char *	to,
		double	val
	)

Convert between different units.

Parameters

from	Unit of the value to convert (see wreport::Varinfo)
to	Unit to convert to (see wreport::Varinfo)
val	Value to convert

Return values

res	Converted value

Returns: The error indicator for the function (See error.h)

◆ convert_units_allowed()

bool wreport::convert_units_allowed	(	const char *	from,
		const char *	to
	)

Check if conversion is possible among the given units.

Parameters

from	Unit of the value to convert (see wreport::Varinfo)
to	Unit to convert to (see wreport::Varinfo)

Returns: True if conversion is supported, else false.

◆ convert_units_get_mul()

double wreport::convert_units_get_mul	(	const char *	from,
		const char *	to
	)

Cloud type

◆ varcode_parse()

Varcode wreport::varcode_parse ( const char * desc )

Convert a FXXYYY string descriptor code into its short integer representation.

Parameters

desc	The 6-byte string descriptor as FXXYYY

Returns: The short integer code that can be queried with the WR_GET_* macros
