115 ** FUNCTION: JS_sscanf
116 ** DESCRIPTION:
117 ** JS_sscanf() scans the input character string, performs data
118 ** conversions, and stores the converted values in the data objects
119 ** pointed to by its arguments according to the format control
120 ** string.
121 **
122 ** JS_sscanf() behaves the same way as the sscanf() function in the
123 ** Standard C Library (stdio.h), with the following exceptions:
124 ** - JS_sscanf() handles the NSPR integer and floating point types,
125 ** such as JSInt16, JSInt32, JSInt64, and JSFloat64, whereas
126 ** sscanf() handles the standard C types like short, int, long,
127 ** and double.
128 ** - JS_sscanf() has no multibyte character support, while sscanf()
129 ** does.
130 ** INPUTS:
131 ** const char *buf
132 ** a character string holding the input to scan
133 ** const char *fmt
134 ** the format control string for the conversions
135 ** ...
136 ** variable number of arguments, each of them is a pointer to
137 ** a data object in which the converted value will be stored
138 ** OUTPUTS: none
139 ** RETURNS: JSInt32
140 ** The number of values converted and stored.
141 ** RESTRICTIONS:
142 ** Multibyte characters in 'buf' or 'fmt' are not allowed.
