DESCRIPTION

Ns_Match(a, b)

Compare the beginnings of two strings, case insen

sitively. The comparison stops when the end of the shorter

string is reached. Return NULL if no match, b if match.

Ns_NextWord(line)

Return a pointer to first character of the next

word in a string; words are separated by white space. The re

turned pointer points into the original string. For example,

Ns_NextWord("abc def") returns a pointer to the 'd' in that

string.

Ns_StrCaseFind(s1, s2)

Locate the first occurrence of substring s2 within

string s1 in a case-insensitive manner. The terminating ' ' char

acters are not compared. Returns a pointer that points into s1.

Uses strstr(3) to do its work.

Ns_StrCopy(str)

ns_strcopy(str)

Copy a string or NULL value using Ns_Malloc. The

Ns_StrCopy function is identical to the Ns_StrDup function but

allows for the string parameter to be NULL, in which case Ns_Str

Copy does nothing and returns NULL.

Ns_StrDup(str)

ns_strdup(str)

Copy a string using Ns_Malloc. The Ns_StrDup func

tion calls Ns_Malloc to allocate enough memory to make a copy of

the given string.

Ns_StrNStr(pattern, expression)

Search through pattern for expression, case insen

sitively. Return a pointer that points to where the match begins

within pattern, or NULL if expression is not contained in pat

tern.

Ns_StrToLower(string)

Convert string to lowercase. Returns pointer to

original string. Original string will be modified.

Ns_StrToUpper(string)

Convert string to uppercase. Returns pointer to

original string. Original string will be modified.

Ns_StrTrim(string)

Trim leading and trailing white space from string.

A pointer to the trimmed string will be returned, which will be

in the original string. Do not lose your original pointer to the

string if you later need to free it.

Ns_StrTrimLeft(string)

Trim leading white space from string. A pointer to

the trimmed string will be returned, which will be in the origi

nal string. Do not lose your original pointer to the string if

you later need to free it.

Ns_StrTrimRight(string)

Trim trailing white space from string. The original

string pointer will be returned, but the string will have been

modified: a ' 's will have been placed right after the last non

whitespace character of the string.

Ns_StringPrint(string)

Print a string to stdout.
