read.c

This is an example of doing a synchronous read operation, and how to process the returned results.

To compile this example on Unix:

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

To compile this example on Windows:

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

To link this example on Unix:

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

To link this example on Windows:

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