95 fields. If it is successful, a
96 standard stream descriptor is returned which should be passed to
97 subsequent FTP operations.
98 On failure, NULL is returned and
100 will have the error code returned by the foreign server.
103 attempts to issue a server CD command to the directory named in
105 On success, zero is returned. On failure, the error code from the server.
108 returns the server failure code for the last operation (useful for seeing
109 more about what happened if you're familiar with FTP error codes).
111 returns a human readable version of the supplied server failure code.
114 attempts to retreive the file named by the
116 argument (which is assumed to be relative to the FTP server's current directory,
119 and returns a new FILE* pointer for the file or NULL on failure. If
121 is non-NULL, the contents of the integer it points to will be used
122 as a restart point for the file, that is to say that the stream
125 bytes into the file gotten (this is handy for restarting failed
126 transfers efficiently). If the seek operation fails, the value
132 returns the last modification time of the file named by the
134 argument. If the file could not be opened or stat'd, 0 is returned.
137 returns the size in bytes of the file named by the
139 argument. If the file could not be opened or stat'd, -1 is returned.

182 the file has been completely read. Use the lower-level routines
183 if multiple gets are required as it will be far more efficient.
186 attempts to create the file named by the supplied

226 utility, later significantly mutated into a more general form as an
227 extension of stdio by Jordan Hubbard. Also incorporates some ideas and
228 extensions from Jean-Marc Zucconi.
