This file includes the definitions for a thread-safe, buffered readline algorithm. It was originally developed by Richard Stevens, but I did some small changes.

Definition in file readline.h.

Function Documentation

u_char* readline (  int  fd, rline_t *  tsd )

This function reads a complete line from a socket and buffers the data which was not needed within this call. Parameters: fd  The file descriptor to read from tsd  The buffer structure used to buffer Returns: The line as an u_char * string on success, NULL on failure. Attention: You have to free() the returned string! Definition at line 78 of file readline.c.

ssize_t writen (  int  fd, const void *  vptr, size_t  n )

This function tries to write n bytes to a file descriptor. It re-tries it on EAGAIN and EINTR. If not all of the data could be written in the first call, it makes more calls to write the rest of the data. Parameters: fd  The filedescriptor to write to. vptr  The pointer to the data to write n  The size of the data to write Returns: The number of bytes written.
