-
- An interface to the low-level sndlib functions contained in sndlib/headers.c
- and sndlib/io.c, designed for use by the resample program.
- (sndlibextra.c is a stripped-down version of sndlibsupport.c in RTcmix.)

-/* ---------------------------------------------------- sndlib_create --- */
-/* Creates a new file and writes a header with the given characteristics.
- <type> is a sndlib constant for header type (e.g. MUS_AIFF).
- <format> is a sndlib constant for sound data format (e.g. snd_16_linear).
- (These constants are defined in sndlib.h.) Caller is responsible for
- checking that the header type and data format are compatible, and that
- the header type is one that sndlib can write (is WRITEABLE_HEADER_TYPE()).
- Writes no comment.
-
- NOTE: This will truncate an existing file with <sfname>, so check first!
-
- On success, returns a standard file descriptor, and leaves the file
- position pointer at the end of the header.
- On failure, returns -1. Caller can check errno then.
