I have allocated the memory. I've ran and tested the program and it works without seg-faulting. I'm "pretty" certain that I understand what's going on now with the pointers, although of course I might be wrong.

If I knew what you were actually trying to do I could show a way to do it.
Thanks. I'm building a type of thread-pool, it's a pretty complex design so I didn't want to burden people with the details, but basically the code I provided is initialising the thread-pool structures which hold "task" information. Suffice to say it's currently working, but I'll watch out out seg-faults, maybe run it through valgrinde.

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it:
(1) one is to pass a pointer-to-pointer parameter, like:
int my_malloc(int size, char **pmem)
{
*pmem=(char *)malloc(size);
if(*pmem==NULL)... (11 Replies)

auparse_init
AUPARSE_INIT(3) Linux Audit API AUPARSE_INIT(3)
NAME
auparse_init - initialize an instance of the audit parsing library
SYNOPSIS
#include <auparse.h>
auparse_state_t *auparse_init(ausource_t source, const void *b);
DESCRIPTION
auparse_init initializes an instance of the audit parsing library. The function returns an opaque pointer to the parser's internal state.
It is used in subsequent calls to the library so. The source variable determines where the library looks for data. Legal values can be:
AUSOURCE_LOGS - use audit logs
AUSOURCE_FILE - use a file
AUSOURCE_FILE_ARRAY - use several files
AUSOURCE_BUFFER - use a buffer
AUSOURCE_BUFFER_ARRAY - use an array of buffers
AUSOURCE_DESCRIPTOR - use a particular descriptor
AUSOURCE_FILE_POINTER - use a stdio FILE pointer
AUSOURCE_FEED - feed data to parser with auparse_feed()
The pointer 'b' is used to set the file name, array of filenames, the buffer address, or an array of pointers to buffers, or the descriptor
number based on what source is given. When the data source is an array of files or buffers, you would create an array of pointers with the
last one being a NULL pointer. Buffers should be NUL terminated.
RETURN VALUE
Returns a NULL pointer if an error occurs; otherwise, the return value is an aopaque pointer to the parser's internal state.
