| [out] | **token | this should be a reference to a string buffer in which the token is put. A new buffer will be allocated when *token is NULL and fixed is false. If the buffer is too small to hold the token, the buffer is reallocated with double the size (of limit). If fixed is true, the string buffer may not be NULL and limit must be set to the buffer size. In that case no reallocations will be done. |
| [in,out] | *limit | reference to the size of the token buffer. Will be reset to the new limit of the token buffer if the buffer is reallocated. |
| [in] | fixed | If fixed is false, the token buffer is allowed to grow when needed (by way of reallocation). If true, the token buffer will not be resized. |
