It checks the \fIstring\fR argument to see if it 26 matches the \fIpattern\fR argument. 27 .sp 28 .LP 29 The \fIflags\fR argument modifies the interpretation of \fIpattern\fR and 30 \fIstring\fR. It is the bitwise inclusive \fBOR\fR of zero or more of the 31 following flags defined in the header <\fBfnmatch.h\fR>. 32 .sp 33 .ne 2 34 .na 35 \fB\fBFNM_PATHNAME\fR \fR 36 .ad 37 .RS 18n 38 If set, a slash (\fB/\fR) character in \fIstring\fR will be explicitly matched 39 by a slash in \fIpattern\fR; it will not be matched by either the asterisk 40 (\fB*\fR) or question-mark (\fB?\fR) special characters, nor by a bracket 41 (\fB[\|]\fR) expression. 42 .sp 43 If not set, the slash character is treated as an ordinary character. 44 .RE 45 46 .sp 47 .ne 2 48 .na 49 \fB\fBFNM_IGNORECASE\fR\fR 50 .ad 51 .RS 18n 52 If set, the \fIstring\fR will be transliterated to lower case before doing the 53 actual match. This transliteration is done using \fBtowlower_l\fR(3C), using 54 the locale of the current thread. If no locale is set, then the global locale 55 is used instead. 56 .sp 57 If not set, the match will use \fIstring\fR with no changes, making the match 58 case-sensitive. 59 .RE 60 61 .sp 62 .ne 2 63 .na 64 \fB\fBFNM_NOESCAPE\fR\fR 65 .ad 66 .RS 18n 67 If not set, a backslash character (\fB\e\fR) in \fIpattern\fR followed by any 68 other character will match that second character in \fIstring\fR. In 69 particular, "\fB\e\e\fR" will match a backslash in \fIstring\fR. 70 .sp 71 If set, a backslash character will be treated as an ordinary character. 72 .RE 73 74 .sp 75 .ne 2 76 .na 77 \fB\fBFNM_PERIOD\fR\fR 78 .ad 79 .RS 18n 80 If set, a leading period in \fIstring\fR will match a period in \fIpattern\fR; 81 where the location of "leading" is indicated by the value of 82 \fBFNM_PATHNAME\fR: 83 .RS +4 84 .TP 85 .ie t \(bu 86 .el o 87 If \fBFNM_PATHNAME\fR is set, a period is "leading" if it is the first 88 character in \fIstring\fR or if it immediately follows a slash. 89 .RE 90 .RS +4 91 .TP 92 .ie t \(bu 93 .el o 94 If \fBFNM_PATHNAME\fR is not set, a period is "leading" only if it is the first 95 character of \fIstring\fR. 96 .RE 97 .RE 98 99 .sp 100 .RS 18n 101 If not set, no special restrictions are placed on matching a period. 102 .SH RETURN VALUES 103 .sp 104 .LP 105 If \fIstring\fR matches the pattern specified by \fIpattern\fR, then 106 \fBfnmatch()\fR returns \fB0\fR. If there is no match, \fBfnmatch()\fR returns 107 \fBFNM_NOMATCH\fR, which is defined in the header <\fBfnmatch.h\fR>. If an 108 error occurs, \fBfnmatch()\fR returns another non-zero value. 109 .SH USAGE 110 .sp 111 .LP 112 The \fBfnmatch()\fR function has two major uses. It could be used by an 113 application or utility that needs to read a directory and apply a pattern 114 against each entry. The \fBfind\fR(1) utility is an example of this. It can 115 also be used by the \fBpax\fR(1) utility to process its \fIpattern\fR operands, 116 or by applications that need to match strings in a similar manner. 117 .sp 118 .LP 119 The name \fBfnmatch()\fR is intended to imply \fIfilename\fR match, rather than 120 \fIpathname\fR match. The default action of this function is to match 121 filenames, rather than path names, since it gives no special significance to 122 the slash character. With the \fBFNM_PATHNAME\fR flag, \fBfnmatch()\fR does 123 match path names, but without tilde expansion, parameter expansion, or special 124 treatment for period at the beginning of a filename. 125 .sp 126 .LP 127 The \fBfnmatch()\fR function can be used safely in multithreaded applications, 128 as long as \fBsetlocale\fR(3C) is not being called to change the locale. 129 .SH ATTRIBUTES 130 .sp 131 .LP 132 See \fBattributes\fR(5) for descriptions of the following attributes: 133 .sp 134 135 .sp 136 .TS 137 box; 138 c | c 139 l | l . 140 ATTRIBUTE TYPE ATTRIBUTE VALUE 141 _ 142 CSI Enabled 143 _ 144 Interface Stability Standard 145 _ 146 MT-Level MT-Safe with exceptions 147 .TE 148 149 .SH SEE ALSO 150 .sp 151 .LP 152 \fBfind\fR(1), \fBpax\fR(1), \fBglob\fR(3C), \fBsetlocale\fR(3C), 153 \fBwordexp\fR(3C), \fBattributes\fR(5), \fBfnmatch\fR(5), \fBstandards\fR(5)
