wcsdup - duplicate a wide-character string
SYNOPSIS
#include <wchar.h>
wchar_t *wcsdup(const wchar_t *s);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
wcsdup():
Since glibc 2.10:
_XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
Before glibc 2.10:
_GNU_SOURCE
DESCRIPTION
The wcsdup() function is the wide-character equivalent of the strdup(3) function. It allocates and returns a new wide-character string
whose initial contents is a duplicate of the wide-character string pointed to by s.
Memory for the new wide-character string is obtained with malloc(3), and should be freed with free(3).
RETURN VALUE
The wcsdup() function returns a pointer to the new wide-character string, or NULL if sufficient memory was not available.
ERRORS
ENOMEM Insufficient memory available to allocate duplicate string.
CONFORMING TO
POSIX.1-2008. This function is not specified in POSIX.1-2001, and is not widely available on other systems.

In Windows,
wchar_t *pStr = L"Hello";
works, but I can't find the equivalent to Unix system.
How can I make static stack-memory-based wide character string in C in Unix? (1 Reply)
I have a file that looks like this
2 4 10 500 tim9
5 8 14 700 tim9
3 5 15 432 john1
1 4 12 999 ellen2
So basically what i want to do is fine duplicate names on column 5 and rename it with an extention (i.e. tim9_1 and tim9_2).
so the output file will look like this
2 4 10 500 tim9_1... (1 Reply)
Hi,
How to eliminate the duplicate values in unix? I have a excel file which contains duplicate values.
Need to use this in a script.
Thanks in advance. (3 Replies)
I have following statement and I want to find duplicate word using sed command. How is it possible?
"detect string and remove the duplicate string"
There could be many statements in a file and each line may have duplicate word.
Thanks! (1 Reply)
