| | 43 | Receiving a message can be done in two ways: either the memory is initialized beforehand and the buffer size is given as the third argument, or a 0 pointer is passed, in which case MUSCLE will initialize the memory. In both cases, the memory must be freed by the user. For example: |
| | 44 | {{{ |
| | 45 | size_t sz = 100; |
| | 46 | double *data = (double *)malloc(sz*sizeof(double)); |
| | 47 | if (data) { |
| | 48 | for (int i = 0; !MUSCLE_Will_Stop(); i++) { |
| | 49 | MUSCLE_Receive("exitName", data, &sz, MUSCLE_DOUBLE); |
| | 50 | // do something with the data |
| | 51 | } |
| | 52 | free(data); |
| | 53 | }}} |
| | 54 | or |
| | 55 | {{{ |
| | 56 | size_t sz = 0; |
| | 57 | if (data) { |
| | 58 | for (int i = 0; !MUSCLE_Will_Stop(); i++) { |
| | 59 | double *data = (double *)MUSCLE_Receive("exitName", (void *)0, &sz, MUSCLE_DOUBLE); |
| | 60 | // do something with the data |
| | 61 | // data will have length sz; |
| | 62 | free(data); |
| | 63 | } |
| | 64 | }}} |
