LEARN ABOUT NETBSD
setmode
SETMODE(3) BSD Library Functions Manual SETMODE(3)
NAME
getmode, setmode -- modify mode bits
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <unistd.h>
void *
setmode(const char *mode_str);
mode_t
getmode(const void *set, mode_t mode);
DESCRIPTION
The setmode() function accepts a string representation of a file mode change, compiles it to binary form, and returns an abstract representa-
tion that may be passed to getmode(). The string may be an numeric (octal) or symbolic string of the form accepted by chmod(1), and may rep-
resent either an exact mode to set or a change to make to the existing mode.
The getmode() function adjusts the file permission bits given by mode according to the compiled change representation set, and returns the
adjusted mode. While only the permission bits are altered, other parts of the file mode, particularly the type, may be examined.
Because some of the possible symbolic values are defined relative to the file creation mask, setmode() may call umask(2), temporarily chang-
ing the mask. If this occurs, the file creation mask will be restored before setmode() returns. If the calling program changes the value of
its file creation mask after calling setmode(), setmode() must be called again to recompile the mode string if getmode() is to modify future
file modes correctly.
If the mode passed to setmode() is invalid, setmode() returns NULL.
EXAMPLES
The effects of the shell command 'chmod a+x myscript.sh' can be duplicated as follows:
const char *file = "myscript.sh";
struct stat st;
mode_t newmode;
stat(file, &st);
newmode = getmode(setmode("a+x"), st.st_mode);
chmod(file, newmode);
ERRORS
The setmode() function may fail and set errno for any of the errors specified for the library routines malloc(3) or strtol(3). In addition,
setmode() will fail and set errno to:
[EINVAL] The mode argument does not represent a valid mode.
SEE ALSO
chmod(1), stat(2), umask(2), malloc(3)
HISTORY
The getmode() and setmode() functions first appeared in 4.4BSD.
BUGS
Each call to setmode allocates a small amount of memory that there is no correct way to free.
The type of set should really be some opaque struct type used only by these functions rather than void *.
