Syntax
Description
message = ferror(fid)
returns the error string
message
. Argument fid
is a file identifier associated with an open file (see fopen
for a complete description of fid
).
message = ferror(fid, 'clear')
clears the error indicator for the specified file.
[message,errnum] = ferror(...)
returns the error status number errnum
of the most recent file I/O operation associated with the specified file.
If the most recent I/O operation performed on the specified file was successful, the value of message
is empty and ferror
returns an errnum
value of 0
.
A nonzero errnum
indicates that an error occurred in the most recent file I/O operation. The value of message
is a string that can contain information about the nature of the error. If the message is not helpful, consult the C run-time library manual for your host operating system for further details.
