| 1008 * FUNCTION: pkix_UTF8_to_UTF16 | |
| 1009 * DESCRIPTION: | |
| 1010 * | |
| 1011 * Converts array of bytes pointed to by "utf8String" with length of | |
| 1012 * "utf8Length" into a freshly allocated UTF-16 string and stores a pointer | |
| 1013 * to that string at "pDest" and stores the string's length at "pLength". The | |
| 1014 * caller is responsible for freeing "pDest" using PKIX_PL_Free. | |
| 1015 * | |
| 1016 * PARAMETERS: | |
| 1017 * "utf8String" | |
| 1018 * Address of array of bytes representing data source. Must be non-NULL. | |
| 1019 * "utf8Length" | |
| 1020 * Length of data source. Must be even. | |
| 1021 * "pDest" | |
| 1022 * Address where data will be stored. Must be non-NULL. | |
| 1023 * "pLength" | |
| 1024 * Address where data length will be stored. Must be non-NULL. | |
| 1025 * "plContext" | |
| 1026 * Platform-specific context pointer. | |
| 1027 * THREAD SAFETY: | |
| 1028 * Thread Safe (see Thread Safety Definitions in Programmer's Guide) | |
| 1029 * RETURNS: | |
| 1030 * Returns NULL if the function succeeds. | |
| 1031 * Returns a String Error if the function fails in a non-fatal way. | |
| 1032 * Returns a Fatal Error if the function fails in an unrecoverable way. | |
