The char * gets (char * str) function in Standard C library reads a line from stdin and stores it inside the string pointed by str. It stops when the end-of-file or newline

The int sprintf function (char * str, const char * format, ...) in the standard C library sends the formatted output to a string str.

The int vfprintf function (FILE * stream, const char * format, va_list arg) in the Standard C library sends the formatted output to a stream using a parameter list.

The function int vsprintf (char * str, const char * format, va_list arg) in the standard C library sends the formatted output to a string string using a parameter list.

The int fscanf function (FILE * stream, const char * format, ...) in Library C reads the input formatted from a Stream.

The function int scanf (const char * format, ...) in Library C standard reads input that has been formatted from stdin.

The function int sscanf (const char * str, const char * format, ...) in Library C standard reads the input formatted from a string.

The function int fgetc (FILE * stream) in C Library standard takes the next character (an unsigned char) from the given Stream and increases the position indicator for that Stream.

Char * fgets (char * str, int n, FILE * stream) in Standard C library reads a line from the given Stream and stores it in the string pointed by str. It stops when any of the

The function int fputc (int char, FILE * stream) in Library C writes one character (an unsigned char) defined by the char parameter to the given Stream and increases the position

The function int fputs (const char * str, FILE * stream) in the Standard C library writes a string to the specified Stream (not writing null characters).

The function int getc (FILE * stream) in C Library standard takes the next character (an unsigned char) from the given Stream and increases the position indicator for that Stream.

The file header named setjmp.h in C Library defines the macro setjmp (), a longjmp () function, and a variable type jmp_buf, to ignore the regular function call and return the

The header file named signal.h in Library C defines a type of variable sig_atomic_t, two function calls, and a number of macros to handle the different signals reported during

Function int raise (int sig) in Library C creates sig signal. The sig parameter is compatible with the SIG macro.

Void function (* signal (int sig, void (* func) (int)) (int) in Library C establishes a function for signal processing (eg a signal handler).

The file header named stdarg.h in Library C defines a type of va_list variable and 3 macros that can be used to retrieve parameters in a function when the number of parameters is

The file header named stddef.h in C Library defines various types of variables and macros. Many of these definitions are also present in other headers.

The header file named stdio.h in Standard C Library defines three variable types, a number of macros and various functions to implement input and output.

Int fclose function (FILE * stream) in Library C closes Stream. All buffers are flushed (erased or moved to the periphery).
