FILE * fout = fopen(FILE_PATH," ")
r |
open for reading |
w |
open for writing (file need not exist) |
a |
open for appending (file need not exist) |
r+ |
open for reading and writing, start at beginning |
w+ |
open for reading and writing (overwrite file) |
a+ |
open for reading and writing (append if file exists |
fclose(fout) close the file
Basic Functions
fgets(char str, int n, FILE stream) |
fgetc(FileOut) -self increment- |
fscanf(FILE stream, FORMAT, char buf) |
ftell(FILE *stream) -rtrn file position long int- |
fputs(const char str, FILE stream) |

fseek(FILE *stream, long int offset, int whence)
offset |
This is the number of bytes to offset from whence. |
whence |
This is the position from where offset is added. It is specified by one of the following constant |
stream |
This is the pointer to a FILE object that identifies the stream. |
fread(void ptr, size, nmemb, FILE stream)
ptr |
This is the pointer to a block of memory with a minimum size of size*nmemb bytes. |
size |
This is the size in bytes of each element to be read. |
nmemb |
This is the number of elements, each one with a size of size bytes. |
stream |
This is the pointer to a FILE object that specifies an input stream. |
