CHRPAKC - Strings and Characters

CHRPAKC is a (very small) collection of C routines for character and string manipulation.

CHRPAKC is a C version of a subset of the FORTRAN CHRPAK collection.

Files you may copy include:

• chrpakc.c, the source code;
• chrpakc.h, the INCLUDE file;
• chrpakc_prb.c, the calling program;
• chrpakc_prb.out, the sample output.

The list of routines includes:

• BYTE2INT converts 4 bytes into an unsigned integer.
• CHAR_INDEX_LAST finds the last occurrence of a character in a string.
• CHAR_PAD "pads" a character with a blank on either side.
• CHRMON returns an abbreviated month name.
• DIGTEN returns the integer value of a base 10 digit.
• GETBITS returns N bits from an unsigned int X, beginning at position P.
• INT2BYTE converts an unsigned integer into 4 bytes.
• INTMAX returns the maximum of two integers.
• INTMIN returns the smaller of two integers.
• PRINT_SIZES reports the size in bytes of various data types.
• REVERSE_BYTES_FLOAT reverses the four bytes in a float.
• REVERSE_BYTES_INT reverses the four bytes in an int.
• S_EQI reports whether two strings are equal, ignoring case.
• STRING_CAP capitalizes all the characters in a string.
• STRING_LOW lowercases a string.
• SWAP_BYTES_FLOAT swaps pairs of bytes in a float.
• SWAP_BYTES_INT swaps pairs of bytes in an int.
