[GitHub] [incubator-nuttx] v01d opened a new issue #3206: sem_wait (and others) return -errno instead of -1 and setting errno
v01d opened a new issue #3206:
URL: https://github.com/apache/incubator-nuttx/issues/3206
As per opengroup:
> The sem_wait() and sem_trywait() functions return zero if the calling process successfully performed the semaphore lock operation on the semaphore designated by sem. If the call was unsuccessful, the state of the semaphore is unchanged, and the function returns a value of -1 and sets errno to indicate the error.
I guess while this could be a simple change it could be breaking since many parts of the code may be assuming the current behavior.

Sorry, I was wrong. Code is OK, just wasn't looking at it correctly.
