Description DavidShu 2015-07-24 05:20:46 UTC 
i have encountered an issue when develop socket application in openwrt using uclibc0.9.33 under MIPS architecture.using non-blocking connect,return value is -1, but errno is 0 in any case.I tried to use single proccess, errno is normal error number. I made a lot of testing with other system call,the result is the same.

test case

compile command:
mips-linux-gcc -o test_errno test_errno.c -pthread

or

mips-linux-gcc -o test_errno test_errno.c -lpthread


or

mips-linux-gcc -D_REENTRANT -o test_errno test_errno.c -pthread

The result is the same.
