mgetstr reads a character string from a file str = mgetstr(n, [fd]) n non-negative integer: how many characters should be read. fd an integer: file descriptor as returned by mopen: where characters should be read. The value -1 stands for the last opened file and is the default. str the character string to be read. The mgetstr function attempts to read up to n characters from a file. If end of file is reached before n characters are read, mgetstr returns the properly read values only. As a consequence, when the read cursor is already at the end of the file when mgetstr is called, it returns an empty string no matter what value is provided for n. mclose meof mfprintf fprintfMat mfscanf fscanfMat mget mopen mprintf mput mputstr mseek mtell mdelete "Input/Output functions" section
