-lite: The missing C-lib functions

Libite, or -lite, is a light-weight library of utility functions and missing C library functions.

Helper Macros

• blkdev(dev)

Create block device

• chardev(dev)

Create character device

• erase(path)

  Erase file/directory with remove(). Errors on stderr

• makedir(path)

  Create directory, like mkdir(). Errors on stderr

• makefifo(path)

  Create a FIFO, like mkfifo(). Errors on stderr

• touch(path)

  Create a file, or update mtime. Errors on stderr

• S_ISEXEC(mode_t m)

Mysteriously missing from GLIBC

• UNUSED(var)

Shorter and more readable version of var __attribute__ ((unused))

Generic Functions

• chomp(str)

  Perl like chomp function, chop off last char if newline.

• copyfile(src, dst, len, symlink)

  Like the shell cp(1) and dd(1), can also create symlinks.

• dir(dir, ext, filter, list, strip)

  Wrapper for scandir() with optional filter. Returns a list of names: files and directories that must be freed after use. See the unit test at the bottom for an example.

• fexist(file)

  Check for the existance of a file, returns True(1) or False(0).

• fisdir(path)

  Check for the existance of a directory, returns True(1) or False(0).

• fmode(file)

  Returns the mode_t bits of a file or directory.

• rsync(src, dst, delete, *filter())

  Very simple rsync() to copy files files and directories recursively.

OpenBSD Functions

The following are the popular OpenBSD string functions.

• strlcpy(dst, src, len)
• strlcat(dst, src, len)
• strtonum()

TODO

• Improve documentation, possibly use kdoc or gdoc2 to generate docs from API.
