Hi,
I would like to know if it's possible to append data into a variable, rather than into a file.

realpath
REALPATH(3) BSD Library Functions Manual REALPATH(3)NAME
realpath -- returns the canonicalized absolute pathname
SYNOPSIS
#include <stdlib.h>
char *
realpath(const char *restrict file_name, char *restrict resolved_name);
DESCRIPTION
The realpath() function resolves all symbolic links, extra ``/'' characters, and references to /./ and /../ in file_name. If the
resolved_name argument is non-NULL, the resulting absolute pathname is copied there (it must refer to a buffer capable of storing at least
PATH_MAX characters).
As a permitted extension to the standard, if resolved_name is NULL, memory is allocated for the resulting absolute pathname, and is returned
by realpath(). This memory should be freed by a call to free(3) when no longer needed.
The realpath() function will resolve both absolute and relative paths and return the absolute pathname corresponding to file_name. All com-
ponents of file_name must exist when realpath() is called.
RETURN VALUES
On success, the realpath() function returns the address of the resulting absolute pathname, which is resolved_name if it was non-NULL, or the
address of newly allocated memory. If an error occurs, realpath() returns NULL. If resolved_name was non-NULL, it will contain the pathname
which caused the problem.
VARIANTS
Defining _DARWIN_C_SOURCE or _DARWIN_BETTER_REALPATH before including stdio.h will cause the provided implementation of realpath() to use
F_GETPATH from fcntl(2) to discover the path.
ERRORS
The function realpath() may fail and set the external variable errno for any of the errors specified for the library functions alloca(3),
getattrlist(2), getcwd(3), lstat(2), readlink(2), stat(2), and strdup(3).
LEGACY SYNOPSIS
#include <sys/param.h>
#include <stdlib.h>
The include file <sys/param.h> is necessary.
LEGACY DESCRIPTION
In legacy mode, the last component of file_name does not need to exist when realpath() is called.
SEE ALSO free(3), getcwd(3), compat(5)HISTORY
The realpath() function first appeared in 4.4BSD.
