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