Function Documentation

   size_t wget_vasprintf (char ** strp, const char * fmt, va_list args)
       Parameters
           strp Pointer to hold the string output
           fmt Printf-like format specifier
           args va_list of arguments

       Returns
           Length of the string returned via strp

       Prints arguments to allocated memory and 0-terminates it. The string is returned via the
       first argument. It has to be free()'d by the caller when it is no longer needed.

   size_t wget_asprintf (char ** strp, const char * fmt,  ...)
       Parameters
           strp Pointer to hold the string output
           fmt Printf-like format specifier
           ... List of arguments

       Returns
           Length of the string returned via strp

       Prints arguments to allocated memory and 0-terminates it. The string is returned via the
       first argument. It has to be free()'d by the caller when it is no longer needed.

   char* wget_vaprintf (const char * fmt, va_list args)
       Parameters
           fmt Printf-like format specifier
           args va_list of arguments

       Returns
           Pointer to 0-terminated string in memory

       Prints arguments to memory and returns a pointer to allocated and 0-terminated chunk of
       memory. The return value has to be free()'d by the caller when it is no longer needed.

   char* wget_aprintf (const char * fmt,  ...)
       Parameters
           fmt Printf-like format specifier
           ... List of arguments

       Returns
           Pointer to 0-terminated string in memory

       Prints arguments to memory and returns a pointer to allocated and 0-terminated chunk of
       memory. The return value has to be free()'d by the caller when it is no longer needed.

   size_t wget_vfprintf (FILE * fp, const char * fmt, va_list args)
       Parameters
           fp FILE pointer
           fmt Printf-like format specifier
           args List of arguments

       Returns
           Pointer to 0-terminated string in memory

       Prints arguments to stream fp and returns number of bytes written.

   size_t wget_fprintf (FILE * fp, const char * fmt,  ...)
       Parameters
           fp FILE pointer
           fmt Printf-like format specifier
           ... List of arguments

       Returns
           Pointer to 0-terminated string in memory

       Prints arguments to stream fp and returns number of bytes written.

   size_t wget_vsnprintf (char * str, size_t size, const char * fmt, va_list args)
       Parameters
           str Destination buffer
           size Size of str
           fmt Printf-like format specifier
           args List of arguments

       Returns
           Number of bytes written, or, on truncation, that would have been written

       Prints arguments to buffer str and returns number of bytes written, or on truncation: that
       would have been written.

       If str is NULL the return value are the number of bytes that would have been written.

   size_t wget_snprintf (char * str, size_t size, const char * fmt,  ...)
       Parameters
           str Destination buffer
           size Size of str
           fmt Printf-like format specifier
           ... List of arguments

       Returns
           Number of bytes written, or, on truncation, that would have been written

       Prints arguments to buffer str and returns number of bytes written, or on truncation: that
       would have been written.

       If str is NULL the return value are the number of bytes that would have been written.
