mktemp(3C) mktemp(3C)
NAME
mktemp(), mkstemp() - make a unique file name
SYNOPSIS
Remarks
These functions are provided solely for backward compatibility and importability of applications, and are not recommended for new applica-
tions where portability is important. For portable applications, use instead (see tmpfile(3S)).
DESCRIPTION
replaces the contents of the string pointed to by template by a unique file name, and returns the address of template. The string in tem-
plate should look like a file name with six trailing replaces each with a single byte character from the portable filename character set.
The letter is chosen such that the resulting name does not duplicate the name of an existing file.
makes the same replacement to the template, but also returns a file descriptor for the template file after opening the file for reading and
writing. thus prevents any possible race condition between testing whether the file exists and opening it for use.
RETURN VALUE
returns its argument except when it runs out of letters or an underlying service fails, in which case the result is a pointer to an empty
string
returns an open file descriptor upon successful completion, or -1 if no suitable file could be created.
WARNINGS
It is possible to run out of letters.
and do not check to determine whether the file name part of template exceeds the maximum allowable file name length.
Setting kernel tunable to values greater than 99999 can have an effect on formation of temporary filenames in and
Formation of temporary filenames using process ids may not be supported in future versions of and
