# hdf\_register\_fileload(3)

register a fileload function

## NAME

hdf\_register\_fileload  - register a fileload function

## SYNOPSIS

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

```
void hdf_register_fileload(HDF *hdf, void *ctx, HDFFILELOAD fileload);
```

## ARGUMENTS

hdf - pointer to a head HDF node\
 ctx - pointer that is passed to the HDFFILELOAD function when called\
 fileload - a HDFFILELOAD function

## DESCRIPTION

hdf\_register\_fileload registers a fileload function that overrides the built-in function.  The built-in function uses hdf\_search\_path and ne\_file\_load (based on stat/open/read) to find and load the file on every hdf\_read\_file (including #include).  You can override this function if you wish to provide other file search functions, or load the hdf file from an in-memory cache, etc.

## RETURN VALUE

None
