- .TH curl_strequal 3 "30 April 2004" "libcurl" "libcurl"
- .SH NAME
- curl_strequal, curl_strnequal - case insensitive string comparisons
- .SH SYNOPSIS
- .nf
- #include <curl/curl.h>
- int curl_strequal(char *str1, char *str2);
- int curl_strnequal(char *str1, char *str2, size_t length);
- .fi
- .SH DESCRIPTION
- The
- .B curl_strequal()
- function compares the two strings \fIstr1\fP and \fIstr2\fP, ignoring the case
- of the characters. It returns a non-zero (TRUE) integer if the strings are
- identical.
- .sp
- The \fBcurl_strnequal()\fP function is similar, except it only compares the
- first \fIlength\fP characters of \fIstr1\fP.
- .sp
- These functions are provided by libcurl to enable applications to compare
- strings in a truly portable manner. There are no standard portable case
- insensitive string comparison functions. These two work on all platforms.
- .SH EXAMPLE
- .nf
- if(curl_strequal(name, input))
- printf("Name and input matches\\n");
- if(curl_strnequal(name, input, 5))
- printf("Name and input matches in the 5 first bytes\\n");
- .fi
- .SH AVAILABILITY
- Always
- .SH RETURN VALUE
- Non-zero if the strings are identical. Zero if they are not.
- .SH "SEE ALSO"
- .BR strcmp "(3), " strcasecmp "(3)"
