stringProc2 video filter method

stringProc2

Creates a user-readable string description of the filter instance's current configuration.

void stringProc2(const VDXFilterActivation *fa, const VDXFilterFunctions *ff, char *buf, int maxlen);

Parameters

fa	Pointer to filter activation structure.
ff	Pointer to callback function structure.
buf	Buffer to receive string.
maxlen	Size of the buffer, in bytes. This includes the terminating null.

Thread safety

This method is not thread-safe.

Exceptions

This function must not throw exceptions (see Except()).

Default behavior

If omitted, no default action is taken.

Remarks

This function is the same as stringProc, except that this version supplies the length of the buffer, to avoid buffer overflows. New filters should supply both this function and stringProc; 1.4.10 and earlier will use the the older function, and 1.4.11 will use this version.
