NAME
    cgCreateEffectFromFile - create an effect object from a file

SYNOPSIS
      #include <Cg/cg.h>

      CGeffect cgCreateEffectFromFile( CGcontext context, 
                                       const char * filename,
                                       const char ** args );

PARAMETERS
    context The context to which the new effect will be added.

    filename
            Name of a file that contains the effect's source code.

    args    If args is not NULL it is assumed to be an array of
            NULL-terminated strings that will be passed directly to the
            compiler as arguments. The last value of the array must be a
            NULL.

RETURN VALUES
    Returns a CGeffect handle on success.

    Returns NULL if an error occurs.

DESCRIPTION
    cgCreateEffectFromFile generates a new CGeffect object and adds it to
    the specified Cg context.

    If an error occurs cgGetLastListing can be called to retrieve any
    warning or error messages from the compilation process.

EXAMPLES
      CGcontext context = cgCreateContext();
      CGeffect effect = cgCreateEffectFromFile(context, "filename.cgfx", NULL);

ERRORS
    CG_INVALID_CONTEXT_HANDLE_ERROR is generated if context is not a valid
    context.

    CG_FILE_READ_ERROR is generated if the given filename cannot be read.

    CG_COMPILER_ERROR is generated if compilation fails.

HISTORY
    cgCreateEffectFromFile was introduced in Cg 1.4.
