# vf\_set\_prop\_value(3)

vf\_set\_prop\_value()

## NAME

vf\_set\_prop\_value - vf\_set\_prop\_value()

## SYNOPSIS

**#include \<../vformat/vf\_iface.h\>**

**extern bool\_t vf\_set\_prop\_value**\
 **(**\
\
 	**VF\_PROP\_T \*p\_prop,**\
\
 	**void \*p\_value,**\
\
 	**uint32\_t n\_param,**\
\
 	**vf\_encoding\_t encoding,**\
\
 	**bool\_t copy**\
 **);**

## PARAMETERS

- **VF\_PROP\_T \*p\_prop**

  The property.

- **void \*p\_value**

  Pointer to the data.

- **uint32\_t n\_param**

  Data size or index.

- **vf\_encoding\_t encoding**

  Encoding in use.

- **bool\_t copy**

  Copy the data?.

## DESCRIPTION

Set values associated with a property.

Passing a value of encoding not the same as the current property encoding will cause the property contents to be freed prior to setting the indicated value.

## RETURNS

TRUE \<=\> re-allocation success & encoding correct, FALSE else.
