bl_chrom_name_cmp(3) Library Functions Manual bl_chrom_name_cmp(3) NAME bl_chrom_name_cmp() - Compare chromosome names numerically or lexically LIBRARY #include <biolibc/biostring.h> -lbiolibc -lxtend SYNOPSIS int bl_chrom_name_cmp(const char *name1, const char *name2) ARGUMENTS name1, name2 Names of two chroms DESCRIPTION Perform a numeric comparison of two chrom names. The names may contain a prefix of non-digits, such as "chr". Characters that follow must be a chrom number or letter. Numbers are considered less than letters (e.g. 22 < X). As such, if either is a letter, they are com- pared lexically. If both are numbers, they are converted to integers and compared numerically. Use bl_chrom_name_cmp() only if you need to know which string is < or >. If only checking for equality/inequality, strcmp() will be faster. RETURN VALUES A value < 1 if name1 is numerically < name2 A value > 1 if name1 is numeri- cally > name2 0 if name1 == name2 SEE ALSO strcmp(3) bl_chrom_name_cmp(3)
