What is fseek in matlab?

fseek( fileID , offset , origin ) sets the file position indicator offset bytes from origin in the specified file. status = fseek(___) returns 0 when the operation is successful. Otherwise, fseek returns -1 . Use any of the previous input argument combinations.

Can we use Fseek Ftell in binary?

Do not use fseek() and ftell() to compute the size of a regular file. Understanding the difference between text mode and binary mode is important when using functions that operate on file streams. A binary stream need not meaningfully support fseek calls with a whence value of SEEK_END .

What does Ftell return?

In C language, ftell() returns the current file position of the specified stream with respect to the starting of the file. This function is used to get the total size of file after moving the file pointer at the end of the file.

What is Seek_set?

SEEK_SET – It moves file pointer position to the beginning of the file. SEEK_CUR. SEEK_CUR – It moves file pointer position to given location. SEEK_END. SEEK_END – It moves file pointer position to the end of file.

What is purpose of function Fseek in Matlab?

Is the file identifier specified in FSEEK?

File identifier of an open file, specified as an integer. Before using fseek, you must use fopen to open the file and obtain its fileID. Number of bytes to move from origin, specified as an integer. The value of offset can be positive, negative, or zero.
