The last six characters of \fItemplate\fP must be XXXXXX and these are replaced with a string that makes the filename unique. Since it will be modified, \fItemplate\fP must not be a string constant, but should be declared as a character array. .SH "VALOR DEVUELTO" The \fBmktemp\fP() function always returns \fItemplate\fP. If a unique name was created, the last six bytes of \fItemplate\fP will have been modified in such a way that the resulting name is unique (i.e., does not exist already) If a unique name could not be created, \fItemplate\fP is made an empty string, and \fIerrno\fP is set to indicate the error. .SH ERRORES .TP \fBEINVAL\fP Los últimos seis caracteres de \fItemplate\fP no eran XXXXXX. .SH ATRIBUTOS Para obtener una explicación de los términos usados en esta sección, véase \fBattributes\fP(7). .TS allbox; lb lb lb l l l. Interfaz Atributo Valor T{ \fBmktemp\fP() T} Seguridad del hilo Multi\-hilo seguro .TE .SH "CONFORME A" .\" .SH NOTES .\" The prototype is in .\" .I .\" for libc4, libc5, glibc1; glibc2 follows the Single UNIX Specification .\" and has the prototype in .\" .IR . 4.3BSD, POSIX.1\-2001. POSIX.1\-2008 removes the specification of \fBmktemp\fP(). .SH ERRORES Never use \fBmktemp\fP(). Some implementations follow 4.3BSD and replace XXXXXX by the current process ID and a single letter, so that at most 26 different names can be returned. Since on the one hand the names are easy to guess, and on the other hand there is a race between testing whether the name exists and opening the file, every use of \fBmktemp\fP() is a security risk. The race is avoided by \fBmkstemp\fP(3) and \fBmkdtemp\fP(3). .SH "VÉASE TAMBIÉN" \fBmktemp\fP(1), \fBmkdtemp\fP(3), \fBmkstemp\fP(3), \fBtempnam\fP(3), \fBtmpfile\fP(3), \fBtmpnam\fP(3) .SH COLOFÓN Esta página es parte de la versión 5.10 del proyecto Linux \fIman\-pages\fP.
