\page MIDIPlayerMem Playing a MIDI file from memory
|
||
|
|
|
||
|
|
FluidSynth can be also play MIDI files directly from a buffer in memory. If
|
||
|
|
you need to play a file from a stream (such as stdin, a network, or a
|
||
|
|
high-level file interface), you can load the entire file into a buffer first,
|
||
|
|
and then use this approach. Use the same technique as above, but rather than
|
||
|
|
calling fluid_player_add(), load it into memory and call
|
||
|
|
fluid_player_add_mem() instead. Once you have passed a buffer to
|
||
|
|
fluid_player_add_mem(), it is copied, so you may use it again or free it
|
||
|
|
immediately (it is your responsibility to free it if you allocated it).
