read a character string from a file
str = mgetstr(n, [fd])
Non negative integer: how many characters should be read.
Integer file descriptor as returned by
mopen: where characters should be read. The value
-1stands for the last opened file and is the default.
The character string read.
mgetstr function attempts to read up
n characters from a file. If end of file is
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
fn = SCI + '/ACKNOWLEDGEMENTS'; // absolute path to some file details = fileinfo(fn); // retrieve file details len = details(1); // get file length fd = mopen(fn, 'rt'); // open file as text with read mode str1 = mgetstr(33, fd) // read 33 characters from fd length(str1) // 33 characters read str2 = mgetstr(272, fd) // read the next 272 characters from fd length(str2) // 272 characters read mseek(len - 5); // jump to the 5th character before end of file str3 = mgetstr(10, fd) // try to read 10 characters: returns 5 characters only, no more available length(str3) // yes, there are 5 characters: you just can't see the linefeed :) str4 = mgetstr(10, fd) // read 10 characters: returns empty string length(str4) // empty string mclose(fd); // close file descriptor
