SYNOPSIS

int bl_bed_write(bl_bed_t *bed_feature, bed_field_mask_t field_mask, FILE *bed_stream)

ARGUMENTS

bed_stream      FILE stream to which TSV bed line is written
bed_feature     Pointer to the bl_bed_t structure to output
field_mask      Bit mask indicating which fields to output

DESCRIPTION

Write fields from one line of a bed file to the specified FILE stream. If field_mask is not BL_BED_FIELD_ALL, only selected fields are written.

If field_mask is not BL_BED_FIELD_ALL, fields not indicated by a 1 in the bit mask are written as an appropriate marker for that field, such as a '.', rather than writing the real data. Possible mask values are:

BL_BED_FIELD_NAME BL_BED_FIELD_SCORE BL_BED_FIELD_STRAND BL_BED_FIELD_THICK BL_BED_FIELD_RGB BL_BED_FIELD_BLOCK

The chrom, start, and end fields are required and therefore have no corresponding mask bits. The thickStart and thickEnd fields must occur together or not at all, so only a single bit BL_BED_FIELD_THICK selects both of them. Likewise, blockCount, blockSizes and blockStarts must all be present or omitted, so BL_BED_FIELD_BLOCK masks all three.

RETURN VALUES

BL_WRITE_OK on success BL_WRITE_ERROR on failure (errno may provide more information)
