61 The \fBtmpfile()\fR function creates a temporary file and opens a corresponding
62 stream. The file will automatically be deleted when all references to the file
63 are closed. The file is opened as in \fBfopen\fR(3C) for update (\fBw+\fR).
66 The largest value that can be represented correctly in an object of type
67 \fBoff_t\fR will be established as the offset maximum in the open file
72 Upon successful completion, \fBtmpfile()\fR returns a pointer to the stream of
73 the file that is created. Otherwise, it returns a null pointer and sets
74 \fBerrno\fR to indicate the error.
78 The \fBtmpfile()\fR function will fail if:
85 A signal was caught during the execution of \fBtmpfile()\fR.
