SYNOPSIS

size_t  bl_fastx_qual_len(bl_fastx_t *record)

ARGUMENTS

record  Pointer to the bl_fastx_t structure

DESCRIPTION

Return the length of the qual string of a FASTQ record. The record must be initialized with bl_fastx_init(3) and populated by bl_fastx_read(3) or other means. If the format if the FASTX stream is FASTA, a warning is generated and 0 is returned. Previously used variables may be reused to process another record in the same format (FASTA or FASTQ) or reinitialized by bl_fastx_free(3);

RETURN VALUES

Length of the qual string

EXAMPLES

bl_fastx_t  record = BL_FASTX_INIT;
bl_fastx_init(stdin, &record);
bl_fastx_read(stdin, &record);
printf("Qual string length = %zun", bl_fastx_qual_len(&record));
bl_fastx_free(&record);
