GW2DetermineFileTypeFromMemory

Synopsis

#include "glasswall.core2.api.h"
ft_t GW2DetermineFileTypeFromFile(const char *inputFileBuffer, size_t inputLength);

Returns

If GW2DetermineFileTypeFromMemory cannot discern the file type, it returns the value of the enumeration constant ft_unknown from the enumerated type ft_t ; otherwise, it returns a value from the enumerated type ft_t indicating the file type. A list of the enumeration constants is in the C source header file filetype.h.

public int DetermineFileTypeFromMemory(byte[] inputFileBuffer)

Returns

A value indicating the determined file type - a list of the enumeration constants is in the C source header file filetype.h are consistent with the returned value for this function.

Synopsis

public int GW2DetermineFileTypeFromMemory(byte[] fileBuffer) throws GlasswallException, NullPointerException

public int GW2DetermineFileTypeFromMemory(byte[] fileBuffer, int length) throws GlasswallException, NullPointerException

Note:

The length of the fileBuffer may optionally be specified.

Returns

The GW2DetermineFileTypeFromMemory function returns an enumerator of type ft_t converted to an int. A list of the enumeration constants may be found in the C source header file filetype.h.

A NullPointerException exception will be thrown if fileBuffer is null or empty.

A GlasswallException exception will be thrown if fileBuffer cannot be retrieved.
