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