ferror - Information about file I/O errors
Syntax
message = ferror(fileID)
[message, errnum]
= ferror(fileID)
[...] = ferror(fileID,
'clear')
Description
message = ferror(fileID) returns
the error message for the most recent file I/O operation on the specified
file. If the operation was successful, message is
an empty string. fileID is an integer file
identifier obtained from fopen,
or an identifier reserved for standard input (0),
standard output (1), or standard error (2).
[message, errnum]
= ferror(fileID) returns the
error number. If the most recent file I/O operation was successful, errnum is 0.
Negative error numbers correspond to MATLAB error
messages. Positive error numbers correspond to C library error messages
for your system.
[...] = ferror(fileID,
'clear') clears the error indicator for the specified file.
