NAME

ckalloc - allocate memory safely

SYNOPSIS

void *ckalloc(size)
unsigned int size;

#include <funclist.h>
extern FUNCLIST *OutOfMemoryFuncs;

DESCRIPTION

ckalloc allocates memory from the heap in the same manner as malloc(3). However, if sufficient memory is unavailable, recovery is attempted by calling the list of functions indicated by the OutOfMemoryFuncs global function list (see funclist(3) for details). After these functions are called, the allocation is retried.

If the second attempt fails, ckalloc immediately terminates the process with a message using syserr(3).
