A ASCII character is represented by a single byte. A unicode character is represented by more than one byte. It all depends what you need this information for. Is it possible that you will have international characters in your file?
Maybe an example using the unicode character ä makes it more clear to you:
Code:
$ echo "äbc" |wc -c
5
$ echo "äbc" |wc -m
4

settaskid(2)							   System Calls 						      settaskid(2)

NAME
settaskid, gettaskid, getprojid - set or get task or project IDs SYNOPSIS
#include <sys/types.h> #include <sys/task.h> #include <unistd.h> taskid_t settaskid(projid_t project, int flags); taskid_t gettaskid(void); #include <sys/types.h> #include <sys/task.h> #include <unistd.h> #include <project.h> projid_t getprojid(void); DESCRIPTION
The settaskid() function makes a request of the system to assign a new task ID to the calling process, changing the associated project ID to that specified. The calling process must have sufficient privileges to perform this operation. The flags argument should be either TASK_NORMAL for a regular task, or TASK_FINAL, which disallows subsequent settaskid() calls by the created task. The gettaskid() function returns the task ID of the calling process. The getprojid() function returns the project ID of the calling process. RETURN VALUES
Upon successful completion, these functions return the appropriate task or project ID. Otherwise, -1 is returned and errno is set to indi- cate the error. ERRORS
The settaskid() function will fail if: EACCES The invoking task was created with the TASK_FINAL flag. EAGAIN A resource control limiting the number of tasks or LWPs in the current project or zone has been exceeded. EINVAL The given project ID is not within the valid project ID range. EPERM The {PRIV_PROC_TASKID} privilege is not asserted in the effective set of the calling process. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |MT-Level |Async-Signal-Safe | +-----------------------------+-----------------------------+ SEE ALSO
