From 50a6ac7fb90ad4008b354ff8e72c6ce511dbeb3a Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Tue, 11 Jan 2005 09:41:40 +0000 Subject: Patch from Paul Mundt (lethal) adding an initial librt implementation. I then reworked the syscall handling and made minor cleanups. With luck I've not completely broken his patch... --- librt/mq_unlink.c | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 librt/mq_unlink.c (limited to 'librt/mq_unlink.c') diff --git a/librt/mq_unlink.c b/librt/mq_unlink.c new file mode 100644 index 000000000..aee3478e7 --- /dev/null +++ b/librt/mq_unlink.c @@ -0,0 +1,38 @@ +/* + * mq_unlink.c - remove a message queue. + */ + +#include +#include + +#include + +#ifdef __NR_mq_unlink + +#define __NR___syscall_mq_unlink __NR_mq_unlink +static inline _syscall1(int, __syscall_mq_unlink, const char *, name); + +/* Remove message queue */ +int mq_unlink(const char *name) +{ + int ret; + if (name[0] != '/') { + __set_errno(EINVAL); + return -1; + } + + ret = __syscall_mq_unlink(name + 1); + + /* While unlink can return either EPERM or EACCES, mq_unlink should return just EACCES. */ + if (ret < 0) { + ret = errno; + if (ret == EPERM) + ret = EACCES; + __set_errno(ret); + ret = -1; + } + + return ret; +} + +#endif -- cgit v1.2.3
