You can use malloc to reliably create almost any size array dynamically. This has been the standard approach forever.

NAME
ldap_memfree, ldap_memvfree, ldap_memalloc, ldap_memcalloc, ldap_memrealloc, ldap_strdup - LDAP memory allocation routines LIBRARY
OpenLDAP LDAP (libldap, -lldap) SYNOPSIS
#include <ldap.h> void ldap_memfree(void *p); void ldap_memvfree(void **v); void *ldap_memalloc(ber_len_t s); void *ldap_memcalloc(ber_len_t n, ber_len_t s); void *ldap_memrealloc(void *p, ber_len_t s); char *ldap_strdup(LDAP_CONST char *p); DESCRIPTION
These routines are used to allocate/deallocate memory used/returned by the LDAP library. ldap_memalloc(), ldap_memcalloc(), ldap_memreal- loc(), and ldap_memfree() are used exactly like the standard malloc(3), calloc(3), realloc(3), and free(3) routines, respectively. The ldap_memvfree() routine is used to free a dynamically allocated array of pointers to arbitrary dynamically allocated objects. The ldap_strdup() routine is used exactly like the standard strdup(3) routine. SEE ALSO
