Enumeration Type Documentation

enum VAR_TYPE

Enumeration used to determine the type of data stored in a VAR.

Enumerator
TT_EMPTY	VAR contains no data
TT_ERROR	vresult is valid
TT_LONG	lVal is valid
TT_DOUBLE	dVal is valid
TT_STRING	sVal is valid

enum VRESULT

Enumeration used to return error codes.

Enumerator
VR_OK	Success
VR_OUTOFMEMORY	Failure, Out of memory
VR_BADVARTYPE	Failure, Invalid VAR type
VR_INVALIDARG	Failure, Invalid argument
VR_INVALIDROW	Failure, Invalid row
VR_INVALIDCOL	Failure, Invalid column

Function Documentation

char* VarAllocString

(

const char *

pSrc

)

Allocates a new string for use in a VAR and copies the passed string into it.

Parameters

pSrc	Pointer to the VAR that will be initialized.

Returns

A pointer to the string on success NULL otherwise.

VRESULT VarClear

(

VAR *

pvar

)

Clears a VAR.

Parameters

pvar	Pointer to the VAR that will be freed and initialized.

Return values

VR_OK	Success.
VR_BADVARTYPE	The VAR was invalid (probably uninitialized).

VRESULT VarCopy	(	VAR *	pvarDest,
		const VAR *	pvarSrc
	)

Frees the destination VAR and makes a copy of the source VAR.

Parameters

pvarDest	Pointer to the VAR to receive the copy.
pvarSrc	Pointer to the VAR to be copied.

Return values

VR_OK	Success.
VR_BADVARTYPE	The source and/or the destination are invalid (usually uninitialized).
VR_OUTOFMEMORY	Memory could not be allocated for the copy.

Returns

The return value is one of the following.

void VarFreeString

(

char *

pSrc

)

Frees a string allocated using VarAllocString.

Parameters

pSrc	Pointer to the string to be freed.

void VarInit

(

VAR *

pvar

)

Initializes a VAR.

Parameters

pvar	Pointer to the VAR that will be initialized.
