+***************************************************************************
+** FUNCTION: PR_sscanf
+** DESCRIPTION:
+**     PR_sscanf() scans the input character string, performs data
+**     conversions, and stores the converted values in the data objects
+**     pointed to by its arguments according to the format control
+**     string.
+**
+**     PR_sscanf() behaves the same way as the sscanf() function in the
+**     Standard C Library (stdio.h), with the following exceptions:
+**     - PR_sscanf() handles the NSPR integer and floating point types,
+**       such as PRInt16, PRInt32, PRInt64, and PRFloat64, whereas
+**       sscanf() handles the standard C types like short, int, long,
+**       and double.
+**     - PR_sscanf() has no multibyte character support, while sscanf()
+**       does.
+** INPUTS:
+**     const char *buf
+**         a character string holding the input to scan
+**     const char *fmt
+**         the format control string for the conversions
+**     ...
+**         variable number of arguments, each of them is a pointer to
+**         a data object in which the converted value will be stored
+** OUTPUTS: none
+** RETURNS: PRInt32
+**     The number of values converted and stored.
+** RESTRICTIONS:
+**    Multibyte characters in 'buf' or 'fmt' are not allowed.
