# hdf\_get\_valuef(3)

Return the value of a node in the data set

## NAME

hdf\_get\_valuef  - Return the value of a node in the data set

## SYNOPSIS

```
#include <util/neo_hdf.h>
```

```
char* hdf_get_valuef (HDF *hdf, const char *namefmt, ...)
                      ATTRIBUTE_PRINTF(2,3);
```

## ARGUMENTS

hdf -\> the dataset node to start from\
 namefmt -\> the printf-style format string\
 ... -\> arguments to fill out namefmt

## DESCRIPTION

hdf\_get\_valuef walks the data set pointed to by hdf via namefmt printf expanded with varargs, and returns the string value located there, or NULL if it doesn't exist. This differs from hdf\_get\_value in that there is no default value possible.

## RETURN VALUE

None
