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). .ad l .nh .TS allbox; lbx lb lb l l l.

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) .PP .SH TRADUCCIÓN La traducción al español de esta página del manual fue creada por Juan Piernas y Miguel Pérez Ibars . .PP Esta traducción es documentación libre; lea la .UR https://www.gnu.org/licenses/gpl-3.0.html GNU General Public License Version 3 .UE o posterior con respecto a las condiciones de copyright.
