Combine splitted low & high byte files into one file
Hi all,
i have a binary file splitted into 2 chunks, first part with all high bytes and the second part with all low bytes.
I need to combine the two chunks into one binary file like (eg. exactly the reverse of the splitting method solved in the thread # 130940)
Hi All,

Is this possible that, if free memory is high & swap memory is low, malloc will not be able to allocate memory & return NULL ?:)

Is it possible to have a bash script pick the highest and lowest values of four variables? I've been googling for this but haven't come up with anything. I have a script that assigns variables ($c0, $c1, $c2, and $c3) based on the coretemps from grep/sed statements of sensors. I'd like to also... (5 Replies)
Hi guys,
i have a question about spliting a binary file into 2 chunks.
First chunk with all high bytes and the second one with all low bytes.
What unix tools can i use? And how can this be performed?
I looked in manpages of split and dd but this does not help.

Need some clarification on this....
1. how are kernel/ user spaces and high/low memory related?
2. What do they all mean when i have the kernel command line as:

dpns_chmod
DPNS_CHMOD(3) DPNS Library Functions DPNS_CHMOD(3)NAME
dpns_chmod - change access mode of a DPNS directory/file in the name server
SYNOPSIS
#include <sys/types.h>
#include "dpns_api.h"
int dpns_chmod (const char *path, mode_t mode)
DESCRIPTION
dpns_chmod sets the access permission portion of the mode of a DPNS directory/file in the name server to the bit pattern in mode.
path specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.
mode is constructed by OR'ing the bits defined in <sys/stat.h> under Unix or "statbits.h" under Windows/NT:
S_ISUID 0004000 set user ID on execution
S_ISGID 0002000 set group ID on execution
S_ISVTX 0001000 sticky bit
S_IRUSR 0000400 read by owner
S_IWUSR 0000200 write by owner
S_IXUSR 0000100 execute/search by owner
S_IRGRP 0000040 read by group
S_IWGRP 0000020 write by group
S_IXGRP 0000010 execute/search by group
S_IROTH 0000004 read by others
S_IWOTH 0000002 write by others
S_IXOTH 0000001 execute/search by others
The effective user ID of the process must match the owner of the file or the caller must have ADMIN privilege in the Cupv database. If a
directory is writable and has the sticky bit set, files/directories within that directory can be removed or renamed only if:
the effective user ID of the requestor matches the owner ID of the file or
the effective user ID of the requestor matches the owner ID of the directory or
the file is writable by the requestor or
the requestor has ADMIN privilege in the Cupv database.
RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.
ERRORS
EPERM The effective user ID does not match the owner of the file and the caller does not have ADMIN privilege in the Cupv database.
ENOENT The named file/directory does not exist or is a null pathname.
EACCES Search permission is denied on a component of the path prefix.
EFAULT path is a NULL pointer.
ENOTDIR A component of path prefix is not a directory.
ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.
SENOSHOST Host unknown.
SENOSSERV Service unknown.
SECOMERR Communication error.
ENSNACT Name server is not running or is being shutdown.
