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