TODO(syoyo): refactor function.

Make index zero-base, and also support relative index.

* Map a memory range of this buffer. If successful, mapped points to the specified buffer range. * * @param size (Optional) Size of the memory range

Parse triples with index offsets: i, i/j/k, i//k, i/j

* Copies the specified data to the mapped buffer. Default value writes whole buffer range * * @param data Pointer to the data to copy * @param size

Split a string with specified delimiter character and escape character. https://rosettacode.org/wiki/Tokenize_a_string_with_escaping#C.2B.2B

Tries to parse a floating point number located at s. s_end should be a location in the string where reading should absolutely stop. For example at th

* Create a buffer info descriptor * * @param size (Optional) Size of the memory range of the descriptor * @param offset (Optional) Byte offset from

* Flush a memory range of the buffer to make it visible to the device * * @note Only required for non-coherent memory * * @param size (Optional) S

Parse raw triples: i, i/j/k, i//k, i/j

Extension: parse vertex with colors(6 items)
