async.c

This is an example of doing an asynchronous operation (a read), polling for results, and then printing them out.

Error handling has mostly been omitted for clarity.

To compile this example on Unix:

  cc -I /opt/isode/include -c async.c

To compile this example on Windows:

  cl /nologo /I C:\Progra~1\Isode\include /c async.c

To link this example on Unix:

  cc -o async async.o -L/opt/isode/lib \
      -ldua -lisode -libase -lldap -llber \
      -lisode_ssl -lisode_crypto -lpthread

To link this example on Windows:

  cl /nologo /o async.exe async.obj \
