ttyname(3) -- return name of a terminal
|
|
Returns a pointer to the pathname of the terminal device that is open on the file descriptor desc, or NULL on error (for example, if desc is not connected to a terminal). |
|
tzset(3) -- initialize time conversion information
|
|
The tzset() function initializes the tzname variable from the TZ environment variable. This function is automatically called by the other time conversion functions that depend on the time zone. If the... |
|
ulimit(3) -- get and set user limits
|
|
Warning: This routine is obsolete. The include file is no longer provided by glibc. Use getrlimit(2), setrlimit(2) and sysconf(3) instead. For the shell command ulimit, see bash(1). The ulimit call wi... |
|
undocumented(3) -- undocumented library functions
|
|
This man page mentions those library functions which are implemented in the standard libraries but not yet documented in man pages. |
|
ungetwc(3) -- push back a wide character onto a FILE stream
|
|
The ungetwc function is the wide-character equivalent of the ungetc function. It pushes back a wide character onto stream and returns it. If wc is WEOF, it returns WEOF. If wc is an invalid wide chara... |
|
updwtmp(3) -- append an entry to the wtmp file
|
|
updwtmp() appends the utmp structure ut to the wtmp file. logwtmp() constructs an utmp structure using line, name, host, current time and current process id. Then it calls updwtmp() to append the stru... |
|
usleep(3) -- suspend execution for microsecond intervals
|
|
The usleep() function suspends execution of the calling process for usec microseconds. The sleep may be lengthened slightly by any system activity or by the time spent processing the call. |
|
vector(3) -- Vector data type for Tcl
|
|
The vector command creates a vector of floating point values. The vector's components can be manipulated in three ways: through a Tcl array variable, a Tcl command, or the C API. |
|
watch(3) -- call Tcl procedures before and after each command
|
|
The watch command arranges for Tcl procedures to be invoked before and after the execution of each Tcl command. |
|
wcpcpy(3) -- copy a wide character string, returning a pointer to its end
|
|
The wcpcpy function is the wide-character equivalent of the stpcpy function. It copies the wide character string pointed to by src, including the terminating L'\0' character, to the array pointed t... |
|
wcpncpy(3) -- copy a fixed-size string of wide characters, returning a pointer to its end
|
|
The wcpncpy function is the wide-character equivalent of the stpncpy function. It copies at most n wide characters from the wide-character string pointed to by src, including the terminating L'\0' ... |
|
wcrtomb(3) -- convert a wide character to a multibyte sequence
|
|
The main case for this function is when s is not NULL and wc is not L'\0'. In this case, the wcrtomb function converts the wide character wc to its multibyte representation and stores it at the beg... |
|
wcscasecmp(3) -- compare two wide-character strings, ignoring case
|
|
The wcscasecmp function is the wide-character equivalent of the str- casecmp function. It compares the wide-character string pointed to by s1 and the wide-character string pointed to by s2, ignoring c... |
