  • Function strtol () in C

    Function strtol () in C

     the function long int strtol (const char * str, char ** endptr, int base) in standard c library converts part of the original string in str to a value of long int corresponding to the base base, but must are 2, 8, ..., 36, or special value 0.
  • Function strtoul () in C

    Function strtoul () in C

     the unsigned function long int strtoul (const char * str, char ** endptr, int base) in standard c library converts part of the original string in str to a value of long int corresponding to the base base, given can be 2, 8, ..., 36, or special value 0.
  • Malloc () function in C

    Malloc () function in C

     the malloc () function allocates the requested memory and returns a pointer to it.
  • Function realloc () in C

  • Function setbuf () in C

    Function setbuf () in C

     the function void setbuf (file * stream, char * buffer) in the standard c library defines how a stream is buffered. this function should be called once the file attached to the stream has been opened, but before any input or output operation has taken place.
  • The function setvbuf () in C

    The function setvbuf () in C

     the function int setvbuf (file * stream, char * buffer, int mode, size_t size) in standard c library determines how a stream should be buffered.
  • The sprintf () function in C

    The sprintf () function in C

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

    The function getc () in C

     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.
