Subject: am7xxx-play: check if strtok_r is available
X-Git-Tag: v0.1.3~26
X-Git-Url: https://git.ao2.it/libam7xxx.git/commitdiff_plain/83597605a10608165103f6e6ed61889fbb928511?ds=inline;hp=--cc

am7xxx-play: check if strtok_r is available

On Windows systems, where strtok_r is not available, strtok_s could be
used but this needs the C Run-Time library (msvcrt.dll or msvcr80.dll)
and we can't distribute it.

So for now, when strtok_r is not available, just print a message to warn
the user that the '-o' options is not available.
