The use of an 'enum' strikes me as a slightly odd decision (given > that the kernel uses 'int') but, related to your point below, there > is precedent in, for example, the use of an 'enum' for 'idtype_t' in > waitid() inside glibc, while the kernel type for the argument in > the underlying system call is 'int'. There is also the issue of -fshort-enum. Some people probably expect that they can use that option and still use glibc headers. I do not have any inside knowledge why things are like they are. Presumably we can switch the type member to int. Thanks, Florian
