I don't quite understand?
You have these three:
char b1[PROCPS_BUFSIZE]
char b2[FILENAME_MAX]
char b3[BUFSIZ]
you
RESERVE_CONFIG_BUFFER(b1, PROCPS_BUFSIZE)
RESERVE_CONFIG_BUFFER(b2, FILENAME_MAX)
RESERVE_CONFIG_BUFFER(b3, BUFSIZ)
and
RELEASE_CONFIG_BUFFER(b1)
accordingly.

Where do you need "sizeof(PROCPS_BUFSIZE)" as opposed to
"PROCPS_BUFSIZE", for example?

What am i missing?

cheers,
