60 * SLAPD Memory allocation macros
62 * Unlike ch_*() routines, these routines do not assert() upon
63 * allocation error. They are intended to be used instead of
64 * ch_*() routines where the caller has implemented proper
65 * checking for and handling of allocation errors.
67 * Patches to convert ch_*() calls to SLAP_*() calls welcomed.
