This struct contains utility methods for platform-independent named pipe operations.
Declared in <bdls_pipeutil.h>
struct PipeUtil;| Name | Description |
|---|---|
isOpenForReading | Return true if the pipe with the specified UTF-8 pipeName exists, the calling process has permission to write to it, and some process is able to read the bytes written to it, and false otherwise. On Windows, this function may block and may write an "empty message", consisting of a single newline. The behavior is undefined unless pipeName is a valid UTF-8 string. Note that even though a process might have the pipe open for reading, this function might still return false because there are not sufficient resources available. |
makeCanonicalName | Load into the specified pipeName the system-dependent canonical pipe name corresponding to the specified baseName. Return 0 on success, and a nonzero value if baseName cannot be part of a pipe name on this system. |
send | Send the specified message to the pipe with the specified UTF-8 pipeName. Return 0 on success, and a nonzero value otherwise. message is output in a single write' operation; consequently, messages that do not exceed the PIPE_BUF value (see []Atomicity) will not be interleaved even when multiple concurrent processes are writing to pipeName. The behavior is undefined unless pipeName is a valid UTF-8 string. |
