U_STABLE int32_t U_EXPORT2 u_vsscanf ( const UChar *  buffer,
const char *  patternSpecification,
va_list  ap 

Read formatted data from a Unicode string. This is identical to u_sscanf, except that it will not call va_start and va_end.

buffer The Unicode string from which to read.
patternSpecification A pattern specifying how u_sscanf will interpret the variable arguments received and parse the data.
ap The argument list to use.
The number of items successfully converted and assigned, or EOF if an error occurred.
