.TH TMPFILE 2 .SH NAME tmpfile, tmpnam \- Stdio temporary files .SH SYNOPSIS .B #include <u.h> .br .B #include <stdio.h> .PP .ta \w'\fLFILE 'u .B FILE *tmpfile(void) .PP .B char *tmpnam(char *s) .SH DESCRIPTION .I Tmpfile creates a temporary file that will automatically be removed when the file is closed or the program exits. The return value is a Stdio .B FILE* opened in update mode (see .IR fopen (2)). .PP .I Tmpnam generates a string that is a valid file name and that is not the same as the name of an existing file. If .I s is zero, it returns a pointer to a string which may be overwritten by subsequent calls to .IR tmpnam . If .I s is non-zero, it should point to an array of at least .B L_tmpnam (defined in .BR <stdio.h> ) characters, and the answer will be copied there. .SH FILES .TF /tmp/tf000000000000 .TP .B /tmp/tf000000000000 template for .I tmpfile file names. .TP .B /tmp/tn000000000000 template for .I tmpnam file names. .SH SOURCE .B /sys/src/libstdio .SH BUGS The files created by .I tmpfile are not removed until .IR exits (2) is executed; in particular, they are not removed on .I fclose or if the program terminates abnormally.
