strcasecmp(3) Library Functions Manual strcasecmp(3)NAMEstrcasecmp, strncasecmp - Perform case-insensitive string comparisonsLIBRARYStandard C Library (libc.so, libc.a)SYNOPSIS#include <strings.h> int strcasecmp( const char *s1, const char *s2 int strncasecmp( const char *s1, const char *s2 size_t n;STANDARDSInterfaces documented on this reference page conform to industry standards as follows: strcasecmp(), strncasecmp(): XPG4-UNIX Refer to the standards(5) reference page for more information about industry standards and associated tags.PARAMETERSPoints to a location containing first string. Points to a location containing the second of two strings referenced. Specifies the maximum number of bytes to compare.DESCRIPTIONThe strcasecmp() function compares the string pointed to by the s1 parameter to the string pointed to by the s2 parameter, while ignoring differences in case. The strncasecmp() function is similar to the strcasecmp function, but also compares size. If the size specified by n is reached before a null, the comparison stops. Note that these functions work for 7-bit ASCII compares only and should not be used in internationalized applications.RETURN VALUESUpon completion, the strcasecmp() function returns an integer whose value is greater than, equal to, or less than 0 (zero), according to whether the s1 string, ignoring case, is greater than, equal to, or less than the s2 string. Upon successful completion, the strncasecmp() function returns an integer whose value is greater than, equal to, or less than 0 (zero), according to whether the s1 array (possibly null-terminated), ignoring case, is greater than, equal to, or less than the s2 string (possi- bly null-terminated).RELATED INFORMATIONFunctions: string(3), strcat(3), strcmp(3), strcpy(3) Standards: standards(5) delim off strcasecmp(3)
