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