om_error_string^⚠

om_get_bytes_per_element^⚠

Get the number of bytes per element. This function will set an error if called for an invalid data type. It only supports array types.

om_get_bytes_per_element_compressed^⚠

Get the number of bytes per element after compression. This function will set an error if called for an invalid data type. It only supports array types.

om_header_size^⚠

Return the size in byte of the header that should be read. Always 40 byte to support legacy 2D files.

om_header_type^⚠

Check if the header is a OM file header and return if its a legacy version or a new version file

om_header_write^⚠

Write an header for newer OM files

om_header_write_size^⚠

The size of a OM header for newer files. Always 3 bytes.

om_trailer_read^⚠

om_variable_get_scale_factor^⚠

om_variable_get_type^⚠

Get the type of the current variable

om_variable_init^⚠

After reading data for the variable, initialize it. This is literally a simple cast to an opaque pointer. Source memory must remain accessible!

om_variable_write_numeric_array^⚠

Write meta data for a numeric array to file

om_variable_write_numeric_array_size^⚠

Get the size of meta attributes of a numeric array if written to a file. Does not contain any data. Only offsets for the actual data.

om_variable_write_scalar^⚠

Write a scalar variable with name and children variables to a destination buffer

om_variable_write_scalar_size^⚠

Get the length of a scalar variable if written to a file. If the scalar is a string, we need to know the length of the string.
