12
14 The fnmatch extension provides an AWK interface to the fnmatch(3) rou‐
15 tine. It adds a single function named fnmatch(), one predefined vari‐
16 able (FNM_NOMATCH), and an array of flag values named FNM.
17
18 The first argument is the filename wildcard to match, the second is the
19 filename string, and the third is either zero, or the bitwise OR of one
20 or more of the flags in the FNM array.
21
22 The return value is zero on success, FNM_NOMATCH if the string did not
23 match the pattern, or a different non-zero value if an error occurred.
24
25 The flags are follows:
26
27 FNM["CASEFOLD"]
28 Corresponds to the FNM_CASEFOLD flag as defined in fnmatch(3).
29
30 FNM["FILE_NAME"]
31 Corresponds to the FNM_FILE_NAME flag as defined in fnmatch(3).
32
33 FNM["LEADING_DIR"]
34 Corresponds to the FNM_LEADING_DIR flag as defined in
35 fnmatch(3).
36
37 FNM["NOESCAPE"]
38 Corresponds to the FNM_NOESCAPE flag as defined in fnmatch(3).
39
40 FNM["PATHNAME"]
41 Corresponds to the FNM_PATHNAME flag as defined in fnmatch(3).
42
43 FNM["PERIOD"]
44 Corresponds to the FNM_PERIOD flag as defined in fnmatch(3).
45
47 Nothing prevents AWK code from changing the predefined variable
48 FNM_NOMATCH, but doing so may cause strange results.
