Detailed Description

Parallel-protected debugging-enhanced wrapper around system malloc().

The bu_malloc() routines can't use bu_log() because that uses the bu_vls() routines which depend on bu_malloc(). So it goes direct to stderr, semaphore protected.

Functions

bu_malloc Allocate storage, with visibility & checking
bu_free Similarly, free storage
bu_realloc Reallocate storage, with visibility & checking
bu_calloc Allocate zero'ed storage
bu_prmem When debugging, print memory map
bu_strdup_body Duplicate a string in dynamic memory
bu_malloc_len_roundup Optimize sizing of malloc() requests
bu_free_array free elements of an array
