Miscellaneous Utility Procedures

These procedures provide additional services.

DTLHash1UnsignedLong

This procedure generates a random 32-bit integer from the key passed.

The syntax is:

DTLStrcmpi

This procedure makes a case-insensitive comparison between two strings that are

standard null-terminated C strings. If Str1 is less than Str2, DTLStrcmpi returns a

negative value. If they are equal, DTLStrcmpi returns 0. If Str1 is greater than Str1,

DTLStrcmpi returns a positive value.

The syntax is:

DTLStrdup

This procedure creates a duplicate of a standard, null-terminated C string. It is the

caller’s responsibility to free this duplicate string when it is no longer needed.

The syntax is:

DTLStrlastchr

This procedure returns a pointer to the last occurrence of a given character in a

standard null-terminated C string. If the character never appears in the string, NULL is

returned.

The syntax is:

DTLStrncat

This procedure copies Str2Len characters from Str2 to position Str1Len and after

in Str1, first using realloc to ensure Str1 is big enough to hold the additional

characters. The procedure returns the pointer to the combined string, which might not

be the same as Str1 if realloc has to move the string.
