| void av_bprint_init | ( | AVBPrint * | buf, | |

| unsigned | size_max | |||
| ) |
Init a print buffer.
| buf | buffer to init | |
| size_init | initial size (including the final 0) | |
| size_max | maximum size; 0 means do not write anything, just count the length; 1 is replaced by the maximum value for automatic storage; any large value means that the internal buffer will be reallocated as needed up to that limit; -1 is converted to UINT_MAX, the largest limit possible. Check also AV_BPRINT_SIZE_* macros. |

Test if the print buffer is complete (not truncated).
It may have been truncated due to a memory allocation failure or the size_max limit (compare size and size_max if necessary).
