NULL is defined to be<datatype> *)0 - this means regardless of the underlying architecture
if p == 0 and p is a pointer it is guaranteed to be unassigned. Therefore
Code:
if (p)
if(p==NULL)
evaluate the same. NULL is fairly new. Old C code uses code like (char**)0 all the time. Example - this is in the strtoul definition on the manpage for systems that have C89 compilers.

sasl_errstring
sasl_errstring(3) SASL man pages sasl_errstring(3)NAME
sasl_errstring - Translate a SASL return code to a human-readable form
SYNOPSIS
#include <sasl/sasl.h>
const char * sasl_errstring(int saslerr,
const char * langlist,
const char ** outlang);
DESCRIPTION
sasl_usererr is called to convert a SASL return code (an integer) into a human readable string. At this time the only language available is
american english written by programmers (aka gobbledygook). Note that a server should call sasl_usererr on a return code first if the
string is going to be sent to the client.
saslerr specifies the error number to convert.
langlist is currently unused; Use NULL.
outlang specifies the desired RFC 1766 language for output. NULL defaults to "en-us," currently the only supported language.
It should be noted that this function is not the recommended means of extracting error code information from SASL, instead application
should use sasl_errdetail(3), which contains this information (and more)
RETURN VALUE
Returns the string. If langlist is NULL, US-ASCII is used.
CONFORMING TO
RFC 4422
