Function Documentation

int explain_mkstemp_on_error

(

char *

templat

)

The explain_mkstemp_on_error function is used to call the mkstemp(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_mkstemp(3) function.

Parameters:

templat

The template, exactly as to be passed to the mkstemp(3) system call. The last six characters of template must be "XXXXXX" and these are replaced with a string that makes the filename unique. Since it will be modified, template must not be a string constant, but should be declared as a character array.

Returns:

The value returned by the wrapped mkstemp(3) system call.

Example:

This function is intended to be used in a fashion similar to the following example:

 int result = explain_mkstemp_on_error(templat);
 if (result < 0)
 {
     ...cope with error
     ...no need to print error message
 }
