![]() ![]() * For file size over PHP_INT_MAX (2 147 483 647), PHP filesize function loops from -PHP_INT_MAX to PHP_INT_MAX. When a file is opened in Unicode mode, input functions translate the data that's read from the file into UTF-16 data. FILE fp fopen ('newfile.txt', 'rt+, ccsUTF-8') Allowed values for ccs encoding are UNICODE, UTF-8, and UTF-16LE. It is the real code, it is a little odd situation: // reading png bytes from fileįILE *fp = fopen("./test/resources/RGBA_8bits.Getting Started Introduction A simple tutorial Language Reference Basic syntax Types Variables Constants Expressions Operators Control Structures Functions Classes and Objects Namespaces Enumerations Errors Exceptions Fibers Generators Attributes References Explained Predefined Variables Predefined Exceptions Predefined Interfaces and Classes Predefined Attributes Context options and parameters Supported Protocols and Wrappers Security Introduction General considerations Installed as CGI binary Installed as an Apache module Session Security Filesystem Security Database Security Error Reporting User Submitted Data Hiding PHP Keeping Current Features HTTP authentication with PHP Cookies Sessions Dealing with XForms Handling file uploads Using remote files Connection handling Persistent Database Connections Command line usage Garbage Collection DTrace Dynamic Tracing Function Reference Affecting PHP's Behaviour Audio Formats Manipulation Authentication Services Command Line Specific Extensions Compression and Archive Extensions Cryptography Extensions Database Extensions Date and Time Related Extensions File System Related Extensions Human Language and Character Encoding Support Image Processing and Generation Mail Related Extensions Mathematical Extensions Non-Text MIME Output Process Control Extensions Other Basic Extensions Other Services Search Engine Extensions Server Specific Extensions Session Extensions Text Processing Variable and Type Related Extensions Web Services Windows Only Extensions XML Manipulation GUI Extensions Keyboard Shortcuts ?

I could also before checking with feof() do something like this fread(NULL, 1, 1, fp) I am asking about this because when I add +1 then the number of bytes read by fread() is really -1 byte less, and as the last byte is inserted 00 byte. ![]() Should I always add this +1 value to this size to read all bytes from binary file or there is some hidden reason that this isn't reading to EOF? struct stat finfo include include include // fd fileno(f) //if you have a stream (e.g.Richard Heathfield : .uk 'Usenet is a strange place. How can I find out the file size in bytes of the file I am opening See FAQs 12.40 and 19.12. It returns false! So I need to read (st_size + 1) and only than all bytes have been read and feof() works correctly. If you have the file descriptor fstat() returns a stat structure which contain the file size. 6 18973 Richard Heathfield Angus Comber wrote: Hello I want to open the entire contents of a binary file (the files are quite small) into memory. I come to this conclusion when I used feof() function to check if there really nothing left in FILE *. Two file identifiers are automatically available and need not be opened. If fopencannot open the file, it returns -1. You use the fidas the first argument to other file input/output routines. ![]() ![]() Opens for writing at the end of the file (appending) without removing the end-of-file (EOF) marker before new data is written to the file. Description fid fopen(filename) (On PCs, fopenopens files for binary read access.) fidis a scalar MATLAB integer, called a file identifier. If the given file exists, its contents are destroyed. If I get the file size's in this way, then allocate a buffer of that size and read exactly that size of bytes there seems to be one byte left over. If the file doesn't exist or can't be found, the fopens call fails. Now I am considering what the st_size field really means and how should I use it. So I intend to use fstat() function and struct stat. I consider reading file of unknown size that I know doesn't change size in the meantime. ![]()
