Fscanf manual

Width. An integer that says how many characters (minimum) this conversion should result in. Precision. A period. followed by an integer who's meaning depends on the specifier. For e, E, f and F specifiers: this is the number of digits to be printed after the decimal point (by default, this is 6).; For g, G, h and H specifiers: this is the maximum number of significant digits to be printed. fscanf(3p) Powered by archmanweb, using mandoc for the conversion of manual pages.

The scanf() function reads input from the standard input stream stdin, fscanf() reads input from the stream pointer stream, and sscanf() reads its input from the character string pointed to by str. The vfscanf () function is analogous to vfprintf(3) and reads input from the stream pointer stream using a variable argument list of pointers (see stdarg(3).

Fscanf function is used to read data from the file. It takes two parameter streams and formats. We can format our data using various placeholders according to the type of input we want to read from the file. This function is helpful when we want to read specific data from the file and do not need to read the whole stream. Recommended Articles. The scanf() function reads input from the standard input stream stdin, fscanf() reads input from the stream pointer stream, and sscanf() reads its input from the character string pointed to by str. The vfscanf () function is analogous to vfprintf (3) and reads input from the stream pointer stream using a variable argument list of pointers (see stdarg (3). The function fscanf() is similar to sscanf(), but it takes its input from a file associated with stream and interprets the input according to the specified format, which is described in the documentation for sprintf().

The radix character is. int, fscanf (FILE *__stream, const char *__fmt,) int, fscanf_P (FILE *__stream, const char *__fmt,) int, scanf (const char *__fmt,).
