The fwrite function is not returning error, if the file was removed.
The fwrite function call is not returning error, when the file it writes to is removed, please advise on how to find if the file already opened and being written by a program is removed manually or by some other process.
please see the code below,
the above code was executed, I just left the file alone during the first two loops and then removed the file during the sleep and after that as well, the program is printing the success message, even though the file is not available.
I have two string returning function in ESQL/C
char *segment_name(lbuffer)
char *lbuffer;
{.....
and
char *get_bpdvalue(f_name)
char *f_name;
{......
both declared above main()
char *get_bpdvalue();
char *segment_name();
my problem is segment_name works on sprintf and strcpy... (5 Replies)
hi all,

hi
how can I return multiple values from a C function. I tried the following:
#include <stdio.h>
void foo(int id, char *first_name, char *last_name)
{

this is just an example to illustrate my problem... real code makes
use of the "id" parameter.

Is there some built in command or way of... (3 Replies)

ARRAYS
XPC arrays are collections of XPC objects ordered by index. The index is zero-based. XPC arrays are contiguous, and values must exist at all
indexes between zero and the greatest index of the array. A hole in the array can be simulated by using a null object as returned by
xpc_null_create(3).
CREATION
The xpc_array_create() function returns a newly created array. The caller may optionally provide objects, a C array of XPC object references,
to initialize the array. The count is used to specify the size of the C array. If objects is NULL, then count must be zero. If count speci-
fies more elements than are actually present in values or if values is NULL and count is non-zero, the behavior is undefined.
GETTING AND SETTING VALUES
The xpc_array_append_value() function may be used to append a value to the end of an array. This operation increases the count of the values
in the array by one.
The value of a specific index in the array may be set using the xpc_array_set_value() function. The value must be non-NULL, and the index
must already exist (i.e. less than the count provided at creation or extended through previous append operations).
The value at a specific index of an array may be retrieved using the xpc_array_get_value() function. The result of getting a non-existing
index (i.e. one that was not specified at creation or through a previous append operation) in undefined.
PRIMITIVE GET AND SET FUNCTIONS
Various functions exist for retrieving primitive C and operating system types directly from an array without the need for an intermediate
boxed object. See xpc_object(3) for more information.
The special XPC_ARRAY_APPEND constant may be used to append a value to the end of the array instead of operating on a specific index.
