@deftypefn Replacement int mkstemps (char *@var{template}, int @var{suffix_len})
|
|
||||||
|
|
||||||
Generate a unique temporary file name from @var{template}.
|
|
||||||
@var{template} has the form:
|
|
||||||
|
|
||||||
@example
|
|
||||||
@var{path}/ccXXXXXX@var{suffix}
|
|
||||||
@end example
|
|
||||||
|
|
||||||
@var{suffix_len} tells us how long @var{suffix} is (it can be zero
|
|
||||||
length). The last six characters of @var{template} before @var{suffix}
|
|
||||||
must be @samp{XXXXXX}; they are replaced with a string that makes the
|
|
||||||
filename unique. Returns a file descriptor open on the file for
|
|
||||||
reading and writing.
