create_sample - Constructs a new sample structure of the specified type. Allegro
game programming library.
SAMPLE *create_sample(int bits, int stereo, int freq, int
Constructs a new sample structure of the specified type. Read chapter
"Structures and types defined by Allegro" for an internal
description of the SAMPLE structure. The `bits' parameter can be 8 or 16,
`stereo' can be zero for mono samples and non-zero for stereo samples, `freq'
is the frequency in hertz, and `len' is the number of samples you want to
allocate for the full sound buffer.
Returns a pointer to the created sample, or NULL if the sample could not be
created. Remember to free this sample later to avoid memory leaks.
