UNIT TEST This program has unit tests for internal implementation. Please refer to the manual of axfer-transfer for details. COMPATIBILITY TO APLAY The axfer is designed to be compatible to aplay(1) as much as possible. In command line, executions of aplay/arecord files under $PATH runs axfer with compatibility mode if filesystem has symbolic link from the aplay/arecord to axfer. $ ln -s aplay axfer $ ln -s arecord axfer A string to which arg[0] points When args[0] in run time points to string ended with 'aplay', it has the same meaning of playback direction. When it points to string ended with 'arecord', it has the same meaning of capture direction. Options acknowledged as list subcommand Options of -l , --list-devices , -L , --list-pcms are acknowledged as list subcommand. Without them, the run time performs transfer subcommand.
