The functions fread/fwrite are used for reading/writing data from/to the file opened by fopen function. Size_t fwrite(const void *ptr, size_t size, size_t nmemb, FILE *stream) Size_t fread(void *ptr, size_t size, size_t nmemb, FILE *stream) The fopen() function returns a FILE stream pointer on success while it returns NULL in case of a failure. The initial file position for reading is at the beginning of the file, but output is always appended to the end of the file.
The file is created if it does not exist. ‘a+’ : Open for reading and appending (writing at end of file).The stream is positioned at the end of the file. ‘a’ : Open for appending (writing at end of file).The stream is positioned at the beginning of the file. The file is created if it does not exist, otherwise it is truncated. ‘w’ : Truncate file to zero length or create text file for writing.The first argument is a pointer to a string containing name of the file to be opened while the second argument is the mode in which the file is to be opened. The fopen() function is used to open a file and associates an I/O stream with it.
In this article, we will cover the following functions that are popularly used in file handling : fopen()įILE *fopen(const char *path, const char *mode) Hope this article will clear the top layer of this multilayer aspect. Here in this article I try to bring in the very basic of file handling. Through file handling, one can perform operations like create, modify, delete etc on system files. This aspect of programming involves system files. Any system programmer would learn it as one of his/her initial programming assignments.
