40 * SLAPD Memory allocation macros
42 * Unlike ch_*() routines, these routines do not assert() upon
43 * allocation error. They are intended to be used instead of
44 * ch_*() routines where the caller has implemented proper
45 * checking for and handling of allocation errors.
47 * Patches to convert ch_*() calls to SLAP_*() calls welcomed.
