| 17 * DESCRIPTION: | |
| 18 * | |
| 19 * This function creates an InfoAccess from the method provided in "method" and | |
| 20 * the GeneralName provided in "generalName" and stores the result at | |
| 21 * "pInfoAccess". | |
| 22 * | |
| 23 * PARAMETERS | |
| 24 * "method" | |
| 25 * The UInt32 value to be stored as the method field of the InfoAccess. | |
| 26 * "generalName" | |
| 27 * The GeneralName to be stored as the generalName field of the InfoAccess. | |
| 28 * Must be non-NULL. | |
| 29 * "pInfoAccess" | |
| 30 * Address where the result is stored. Must be non-NULL. | |
| 31 * "plContext" | |
| 32 * Platform-specific context pointer. | |
| 33 * THREAD SAFETY: | |
| 34 * Thread Safe (see Thread Safety Definitions in Programmer's Guide) | |
| 35 * RETURNS: | |
| 36 * Returns NULL if the function succeeds. | |
| 37 * Returns a Fatal Error if the function fails in an unrecoverable way. | |
