Synopsis

Return values

wopen and wcreat return the new file descriptor, or -1 if an error occurred(in which case, errno is set appropriately).

Detailed description

The wcreat function is the same as:

wopen(path, O_CREAT | O_TRUNC | O_WRONLY, mode);

         
Limitation :Creating a new file doesn’t alter the time stamp of parent directory, created entry has only two time stamps access and modification timestamps.
Creation time stamp of the file is not supported, here accesstime stamp is equal to modification time stamp.
