NAME
copylist - copy a file into memory SYNOPSIS
cc [ flag ... ] file ... -lgen [ library ... ] #include <libgen.h> char *copylist(const char *filenm, off_t *szptr); DESCRIPTION
The copylist() function copies a list of items from a file into freshly allocated memory, replacing new-lines with null characters. It expects two arguments: a pointer filenm to the name of the file to be copied, and a pointer szptr to a variable where the size of the file will be stored. Upon success, copylist() returns a pointer to the memory allocated. Otherwise it returns NULL if it has trouble finding the file, calling malloc(), or reading the file. USAGE
The copylist() function has a transitional interface for 64-bit file offsets. See lf64(5). EXAMPLES
Example 1 Example of copylist() function. /* read "file" into buf */ off_t size; char *buf; buf = copylist("file", &size); if (buf) { for (i=0; i<size; i++) if (buf[i]) putchar(buf[i]); else putchar(' '); } } else { fprintf(stderr, "%s: Copy failed for "file". ", argv[0]); exit(1); } ATTRIBUTES

When compiling multithreaded applications, the _REENTRANT flag must be defined on the compile line. This flag should only be used in mul- tithreaded applications. SunOS 5.11 29 Dec 1996 copylist(3GEN)

NAME
bufsplit - split buffer into fields SYNOPSIS
cc [ flag ... ] file ... -lgen [ library ... ] #include <libgen.h> size_t bufsplit(char *buf, size_t n, char **a); DESCRIPTION
bufsplit() examines the buffer, buf, and assigns values to the pointer array, a, so that the pointers point to the first n fields in buf that are delimited by TABs or NEWLINEs. To change the characters used to separate fields, call bufsplit() with buf pointing to the string of characters, and n and a set to zero. For example, to use colon (:), period (.), and comma (,), as separators along with TAB and NEWLINE: bufsplit (":., ", 0, (char**)0 ); RETURN VALUES
The number of fields assigned in the array a. If buf is zero, the return value is zero and the array is unchanged. Otherwise the value is at least one. The remainder of the elements in the array are assigned the address of the null byte at the end of the buffer. EXAMPLES
Example 1 Example of bufsplit() function. /* * set a[0] = "This", a[1] = "is", a[2] = "a", * a[3] = "test" */ bufsplit("This is a test ", 4, a); NOTES
bufsplit() changes the delimiters to null bytes in buf. When compiling multithreaded applications, the _REENTRANT flag must be defined on the compile line. This flag should only be used in mul- tithreaded applications. ATTRIBUTES
